History of Screws and Screw Threads

In this edition, we are going to discuss about how screws, the most relevant fastener came into being. But before debunking into their history, let’s go through a formal introduction.

What is a screw?
A screw is a small metallic object (shaft), featuring a corkscrew-shaped channel present on its surface. This kind of fastener is used to bind two objects together and a screwdriver is required to fasten such objects.

Archimedes in 200 BC had originally developed the principle of screw and used this technique to build devices, so as to raise water from the ground level or beneath of that. According to the archaeologists, the forerunner of the modern fasteners, such as screws is found in some artefacts, dating back to early Egyptian and Greek eras. The rulers of Alexandria used them in their automations and ammunitions. With the advent of the Renaissance era, the screw thread attachments and their applications were started to be used in bits and pieces. One of the most common forms in the latter historical epochs is a thin metal bar twisted into a helix shape by a smith, which resembles much like today’s hammer, screw driver and nails.

The second most commonly used form of this particular fastener is the one, which was cut using saws and gravers. The screw thread technology started to be used on a broader scale in the 18th century. However, it is believed that the screw thread technology was invented by Archytas of Tarentum in 400 BC. He is also known as the founder of mechanics and was a strong contender of Plato. Its application was used for the first time in farms to extract oil from olive and grape juices.

The oil ranches in Pompeii used to work on the screw principle. These fasteners were also seen used in manufacturing of firearms. Earlier, ammunition such as guns were only used by the Royal bodyguards, but soon the common soldiers also started using this weapon. Thus, it became necessary to reduce the cost of the manufacture of the handguns. On one hand, a nation had to spend a fortune saving the ruler and on the other hand, they had to spend a fortune protecting the common mass as well. The two contributing factors, where this expenditure could be slashed off lay heavily in implementing the barrel and screw threads to accumulate a firearm. As the only solution relied upon the development of a rotating device (lathes), it was no surprising that these two techniques even evolved simultaneously.

History of ScrewsModern Screws
With each passing day, the technology as well as the usage continued to grow and in 19th century, the screws became a relevant part of the hardware supplies. The Robertson screw became hugely popular with the beginning of the 19th century. In 1908, Canadian scientist P.L. Robertson invented the square-drive screws and then 28 years later; Phillips head screws came into being. While the Robertson fasteners were considered the first recess-drive kind fastener, the Phillips Head was extensively used for the gasoline cars.

History of ScrewsSome Recent Updates about Screws
Hey did you know recently the Queen of England gave the green signal to impart power to the Windsor Castle through hydroelectricity? It was carried out by using turbines hugely based on Archimedes’ screw principle. The 40 ton weighing Archimedes’ Screws were set-up at Romney Weir across the Thames River. The turbines exactly look like the screw invented by this Greek mathematician.

In the ancient city of Qsar in Egypt, an ancient mechanical tool was discovered. It appears to be a giant screw, which is believed to be used in ancient times for squeezing out oil from olives.

A Retrospect to the Standard Screw Sizes

The use of fasteners has grown extensively worldwide, increasing the need of coming up with standard screw sizes. Standardization prevents the use of improper screws, and ensures screws are compatible with the materials being used and are appropriate for the project at hand. Screw dimensions include the driver type — such as flat, Phillips or hex — length, shank diameter and threads per inch.

The demand for fasteners has extensively grown globally, especially in the world of online marketing. This growing demand has simultaneously increased the requirement for standard sizing of these hardware supplies.

By classification, the hassle of each time landing up with screws with different patterns and lengths can be greatly avoided. This even ensures that these rivets become comme il faut with the materials, being used in the construction or any build-up project. The various dimensions of these fasteners demand ofr use of various type of screwdrives, such as hex, Phillips, flat determining the shank diameter, length and threads per inch.

Screw’s numbering system

when standardization was done, the screws were put into 2 distinct numbering systems; the metric and U.S numbering systems. The metric measuring system lists out the diameter of these rivets in millimeters first and then secondly in thread pitch. The examples for this category include 6 mm x 1.0, 4 mm x 0.7, 5 mm x 0.8 etc. The U.S stadnard measurement system inlcudes screw with diameter sizes as 0, 1, 2 ,3, 4, 5, 6, 7, 8, 9, 10, 12, 14 and 16 and even in fractional sizes ranging from  1/4″ to 2″ in 1/16″. This is followed by threads and dash per inch falling between 6 and 80.

Diameter of screws

The first number metioned in the size charts for diameter must match the inner diamter of the washers ad nuts applied to them. The diameter of the rivet is measured at the shaft, just below the screw head. The diamter size ranging from 0 to 16 is declared by the American Society of Mechanical Engineers, thereby enabling the hardware sizing system to be extensively adopted worldwide. This kind of measurement made in standard U.S fractions was recently added and countries outside of America  are also seen following this standardization.

Length of screws

While the pan head screw’s length is measured from the flat end of its round head to its tip, the length of the flat head screws measure from the top of the head to the tip of the rivet.

The length is the third item typically listed in the size chart and is identified by an ‘x’ symbol. For instance, a #8-20 x 3/4″ screw features 20 threads per inch and a shaft measuring 3/4″ in length and a 5/8-24 x 1″ screw has a diameter of 5/8″, 24 threads per inch and has a 1″ shaft.

There are some fasteners, which are measured as per the threads per inch sizing, execpt for their length and diameter such as 5/16 x 1/2″ and #10 x 1″

Threading of screws

This kind of measurement is at number 2 in the chart of standard screw sizes. The hyphen refers to the number of threads of screw shaft per inch. For e.g. a 1/4-28 sized screw has diameter of 1/4″ along-with 28 threads per inch and a #6-32 screw has 32 threads per inch on its shaft.

Salient Features of Clutch Head Screws

If you happen to see some kind of odd bow-tie shaped screw slots on your door or window pane, you’ve probably discovered the clutch head screws.  Such fasteners were extensively used in the auto industry from the 1940s through the 1960s. In 1970s, few of these screws also paved their way into travel trailer manufacturing industries as well.

10X High security clutch screws

Clutch head screws are also known as One Way Screws and ‘Security Screws‘. These specially designed fasteners are used for lasting installations. These are easy to use and can be installed using a normal screwdriver. The head of such kind of fastener features a normal drive and slanted rear face, which prevents the screwdriver from applying torque when trying to loosen these fasteners.

Once implanted, these rivets require typical drilling application for removal from the holes. However, you can even fetch for a special kind of driver bit to undo them.

Steel Clutch Head screws

In order to unscrew these rivers, you’re required to use a screwdriver bit of the same shape and size. The clutch head one way screws can be unscrewed in the clockwise direction by using a standard slotted screwdriver. This drive system was probably the worlds first security recess.

Unique Design

This unique feature enables such screws to be tamper-proof, thereby enhancing the security of your house and lessening the risk of robbery and making it impossible for the intruders to tamper the screws. Due to their unique design, there are even ideal for higher torque applications.

Thus, these fasteners are also referred as Jail Head. They are usually self-tappers and are used in applications jail cell hinges and even in domestic window locks and exposed door lock screws.


Standard Clutch Head

Standard Clutch Heads of screws

The clutch head screws are usually of two types: type A and type G. The type A is also known as a standard clutch and usually resembles a bow tie. And the type G resembles a butterfly.

Type G Clutch Head of a screw

These are zinc plated hardened steel and cannot be removed once they are installed. Besides, the countersunk clutch head screws can only be opened by a flat head screw driver


The type A screws were widely used earlier and were commonly seen in 1940s’GM automobiles, including trucks and buses. And the type G rivets are commonly used in the construction of mobile homes and recreational vehicles. You can even find them in your windows and doors, if they’re installed with some odd bow-tie shaped screw slots.

Special features of Clutch Head screws

These are ideal for

  • Public access wooden windows & doors
  • Seating & fencing
  • Prison fittings & fixtures
  • School & college fixings & fixtures
  • Also used in timber applications

Added Benefits

A police survey shows that around 30% of the intruders gain access to the houses through windows. Therefore, it’s utmost necessary to keep your windows secured.

Now Get Rid of Squeaky Floor with Plywood Screws

Plywood screws, which are also known as chipboard screws are self-tapping screws, featuring thin shaft and coarse threads. These fasteners are made up of either wood dust or wood chips and resin, and as the name suggests, these screws are mainly in plywood and other soft wood surfaces.

These rivets are made to clinch this composite surface, so as to withstand loosening. The screws firmly hold either two plywood or any chipboard to other materials, say natural wood.

Apart from wooden works, these screws are highly recommended for squeaky floors as well. Recently one of our esteemed clients faced an issue with pressboard sub-flooring in his 20 years old house. While his upstairs flooring was creaking under the carpet, the downstairs floors jolt the entire house whenever stepped on promptly.

His main concern was to stop those high-pitched annoying sound and if he should go for another layer of plywood over the existing flooring? He was also interested in replacing the entire floor.

Playwood Screws for wood floors

So, this is what we had suggested him. Read on!

Instead of spending huge bucks in replacing the entire flooring, you can always go for an additional layer of plywood, which will definitely resolve all those issues. We highly recommend you to go for thicker material, as thicker the size would be, the degree of sound transmission would be reduced to more extent.

And yes, it’s always possible to fasten the existing wooden surface with the new layering. You’ll have to mark out the old nailing patterns, which should be in a gap of minimum 16 inches. Our aim should be enabling every new fastener with a supporting beam. By doing this, the squeaks will be reduced to a great extent and will even laminate properly the new layers along-with the base.

The plywood screws are the most ideal supplies required for fastening and you can even go for gluing, thereby strengthening the grip even more.

Different Sizes Of Play Wood Screws

In the meanwhile, do not forget about the sap, which pulls this surface up. So, better fasten it with those screws.

And do not try compromising with the quality of the screws, as this is definitely not a place to think about cost-cutting. So purchase the plywood screws in ample quantity and insert screw at every 4-6 inches of gap at the seams and at every 6-8 inches of gap in the field.

This is indeed an effective method, giving away long lasting results.

Much better looking wood floor with playwood screws

If your plywood is of 5-8 inches thick then you should consider those screws, which are at least 2 and 1/2 inches long, so that they can get a nice grip. However be warned that you don’t have any radiant heating line or plumbing beneath this surface.

We suggest you to go for an half inch plywood for the layering and you can even bowl over the seams from the existing surface. You can go cheap on the facings for the plywood to save from the recent hike in their pricing. For instance, you can go for CCX PTS, which exactly works as the ‘A’ grade material or you can even opt for OSB, which works well under the carpet.

The rooms with carpets need a little adjustment, as you would have to manage with the closets and swing doors for proper installation. You need to build a carpet shelf by raising the level of the carpeted areas.

But the major problem arises in areas, where you’re thinking of installing vinyl or linoleum flooring. For this, you’ll need a third layer of chipboard or particle board and so also the have to determine the size and thickness of plywood screws.

Not to mention, stairs are another nightmare. You can easily face trip hazards and in order to prevent this, you should confirm that the building code should have a minimum gap of at least 3-8 inches between the stairs, but the height should not exceed above 8.

Installing ITW Buildex Cement Board Screws

It is always necessary to use the exact type of fastener, say screws in certain conditions, so as to make sure that the installation procedure is executed effectively. And moreover, in the long run the correct usage of screw keeps it firmly fastened to the surface. You should always go for a company, say ITW Buildex, which has been in the hardware supply industry for over four decades, consistently working on enhancing its quality and services.

There are various types of screws available in the market, required for various kinds of jobs. The concrete screw is a very special type of fastener, specially designed to pierce its own threads into an already drilled hole on the surface made up of concrete, block, brick etc. The brand name Cement Board & Fiber Cement Board Screws is popular product, being sold over under this banner.

It was launched in early 80s and was highly popular because of its functionality even when there was less to no option for online branding. Such kind of screw can be easily installed and features enhanced pull-out shield and durable fixing values.

Cement Board & Fiber Cement Board Screws
In the concrete planting industry, the threads of such kinds of metal pieces are popularly called as “High-Low” screws. The threads of such screws enable quick dust removal during the installation process. Such strands also enable the fasteners to pierce in consistently, thereby giving high standard performance. The removal of dirt is relevant, as the dust present in the hole may interfere in the screwing process. Therefore, you should make sure that you’ve removed the dirt from the hole as well as from the thread.

Installing Cement Board ITW Buildex Screws

The installation procedure is quite simple. It can be done in three simple steps:

By using an accurate sized carbide capsized ashlar bit and a hammer drill, you can now drill a pilot hole of about 1/4th inches deep than the suggested anchor fastening

Now you need to clear the hole of the entire fragments

Now by using a standard drilling machine along-with an appropriate Phillips socket/hex, you can insert the metal screw into the already drilled hole until this fastener is completely pierced

You should be rather careful and should take care that you have not over-tightened the ITW Buildex screw, as this will cause the fastener to spin within the hole, thereby stripping the threads.

History of Robertson Screws

If something that can distinguish the Canadian hardware industry from American then it is the Robertson screw, which is also known as the square socket screws and Scrulox.

Square Socket Head Screw

This is one of the highly popular specialized screws, which features a square-shaped socket on its head and the protrusion on the tool is also square-shaped. Both parts of the screw feature a taper, thereby enabling the fastening work much faster and easier as well. Besides, such features also help the screw to stick to the tool tip without any manual support.

In this edition, we’ll be discussing about the history of Robertson screws, which are commonplace in Canada. Read on!

Here is how Robertson Looks

It was a pleasant summer day in 1906, when businessman, Peter Lymburner Robertson was exhibiting a spring-loaded screwdriver before his clients. Accidentally, the driver slipped and he eventually cut his hand. This particular incident provoked him to invent a more advanced screwdriver and some definite set of screws, which could fit this driver. He invented the socket head screw, which revolutionized the entire hardware industry.

Thus, the Robertson screws – the best-kept secret outside of Canada were conceived and became a huge hit soon after it hit the market.

These fasteners are arguably considered as the biggest invention in the fastener industry of the 20th century.

Technical view of a Square Socket Head screw

His specially designed square socket screws and the driver gave a tighter grip than any usual slot and rarely slipped. Robertson worked hard on his invention, which addressed all those issues and finally developed a machine to manufacture screws, with such unique designs.

In those days, the newly developed fasteners were soaring high and had almost dominated the entire hardware industry.

They became favorites among the hardware manufacturers and craftsmen, mostly because of their self-centring feature and that they could be easily driven even by one hand. Moreover, they reduced the risk of product damage and increased the productivity, due to which heavy-duty industries were also clinging towards these fastening objects.

20th centurys Robestson Socket head Screws

One of the early hotshot clients for these screws was the Fisher Body Company, which used to design wooden body parts for Ford cars in Canada. They used 4-6 gross of Robertson screws in manufacturing Model T and they even convinced the Father of these fasteners to invent another specialized type i.e. socket screws for metal, so that they could easily match with the metal body parts of Model A, launched by Fords during that period.

Robertson Screws Used in wooden parts of Old Model Ford cars

But have you ever thought any brand, which became such a huge success didn’t go beyond the boundaries? Why those screws were not found outside of Canada, when they were so much good enough for manufacturers like Ford?

By going deeply into this factor, inventors/designers can learn a great lesson.

When Ford was testing the Robertson screws to employ with their assembly line, they discovered that by using those advanced fasteners, they could actually save up to 2 hours of their assembly time per vehicle.

And in order to protect this huge advantage, they made a license agreement with Robertson, stating that he won’t be having any ownership of his screws in future, so that he couldn’t sell his patent items to other companies.

However, Robertson had slowly expanded his business to Europe, but to his bad luck, World War 1 broke out and his Europe project faced a huge setback. He still emerged as a winner, as this time he was flying high with a blossoming project and felt that signing the agreement with Ford would be in best of his interests.

Robertson Screw Head

As legend goes, somebody else rises and bites the dust. Few years later, another big name rose in the market by the name of Phillips.

Robertson ran his Robertson Screw Company till his death in 1951. Today, this company has grown over 600 employees, with 120 of them belonging to his hometown Ontario in Milton.

Dog Point Set Screw: The Most Commonly Used Set Screw

A socket set screw is a specific type of threaded fastener, which usually does not feature a head. Unlike other kind of commonly used rivets, this metal piece is basically an adjustment device generally used to develop axial chunk. Such kind of screw comes handy and is used for multiple uses. Plus, it is also available in various types, the most common type, being the dog point set screw.

Such type of fastener is used to clutch body parts like collar, gear, sleeve, coupling etc. into an axle, so as to prevent relative oscillation. The socket feature helps such kind of screw to effectively rotate in a desired direction. The sockets are available in various types, including fluted socket, square head, screwdriver slot, hexagon socket and much more in the list.

You should always consider the point of your fastener before purchasing it. You should know which model is suitable for your job. The point of a rivet is the area, which rotates against the shaft during penetration. The point selection is usually done by determining the nature of the functionality. The point is available in various types, which are as follows:

Dog Point Set Screw:

It is the most common type, mostly used for fixing into any permanent location of one surface to the other. It features a broad flattened end, followed by its angular threads ending before just above the tail. The fastener’s end is placed in the already drilled hole in shaft or on a flat surface. It is often replaced with the dowel pinions and always works well against the must rugged surface or hollow tubing.

Flat type:

Such kind of point is used on those surfaces, where parts are always replaced or re-set. IN this frequent application, such kind of point helps prevent damage or any kind of wear and tear.

Knurled Cup:

This type of point is used for permanent locations, including collars, gears, knobs, pulleys and shafts. This particular head is able to resist more amount of vibration.

Plain Cup:

This point is used for style set screw. It is usually used in permanent as well as fluctuating locations mainly on shaft, featuring hardness differential of 10-15 Rockwell C points and in those areas, where the cutting of the cap is acceptable.

You can select any of these above set screws, determining the nature and requirement of your job.

Screw Head Types and their Uses

At Mutual Screw and Supply, we field several calls from our esteemed clients, seeking help in choosing right bit of screw head types, appropriate for their requirements.

Different of screws with different types of Screw heads

Here’s a brief yet comprehensive guide to screw head types and drives. Read on!

When your jobs requires usage of screws then always remember to go for the right type of screw driver. While most of the screws look alike, but their screw heads are rather different, thereby enabling you to go for distinct screw drives, which fit with the heads of your chosen screws. For instance, Phillips and Pozidriv are hard to be distinguished from a distance of 10 feet. But both of these fasteners do feature different heads and simultaneously they require different kinds of screw drives for their installation.

Phillips and Frearson Screw Heads

Here is a list of different types of screw heads.


Phillips Screw Head


Invented by Henry Phillips, this kind of drive was explicitly designed to cam-out (it’s a method in which the screw driver glides out of the screw head, when it is driven and the torque which is required to turn the fastener crosses a certain amount) when the screw was bogged down, so as to prevent any damage occurring to the head, nonetheless affecting the driver. This particular design however created relative difficulty in developing torque, thereby restricting into the old drivers.

Other hardware companies therefore discarded the Phillips concept, as it created a relatively tangled and sunken socket shape in the head of the rivets.

These heads are usually designated in 7 types, depending upon the size of the screws and they include 000, 00, 0, 1, 2, 3, and 4.


A Slotted Screw Head


This is the most commonly used screw drive and is commonplace everywhere in the world, although its traditional usage is declining gradually, because of its slipping nature whenever heavy torque is applied over it.

Phillips Tamper-resistant

A Phillips tamper Resistant Screw Head


Most of the screw drives available in the market are tamper-resistant because of their vagueness. The one-way and breakaway drives fall under this category, which require specialized tools to destroy the rivet while unscrewing them. The high-end quality of such drives is used on home electronics. Such feature even helps the professional technician to repair the equipment easily, without having to return the piece to the manufacturer.


Quadrex Screw Head


Quadrex, which is also known as the Phillips/square screw drive, is actually a combination of Robertson and Phillips screw drives. While an ordinary Robertson or Phillips tool can be used for its application, there is still a specialized tool for it, which enhances the surface area between the rivet and the tool, thereby enabling to handle more torque.

Earlier, this drive was sold under the name Deck Mate, which is now considered as other kind of drive.


Supadriv Screw head



The Supadriv, which is also spelt as ‘Supadrive’ is almost similar to Pozidriv by design and people often get confused between these two.

Anyways, this particular drive can be identified by two of its unique features. It secondary blades are larger and are of equal thickness. Moreover, it has got a superior bit, thereby making the installation procedure more efficient, producing less cam-out.


Pozidriv Screw Head



The Pozidriv is the enhanced version of the Phillips screw drive. It is patented by American Screw Company and Phillips Screw Company. Many consider this name as an abbreviation of ‘positive drive’. The major advantage of such kind of drive is its likelihood to prevent cam-out, thereby enabling greater torque to be employed. As per ANSI, it is considered as type IA and is quite similar with Supadriv screw driver.


Frearson Screw Head


The Frearson, which is also known as the Reed and Prince Screw head type, is somewhat similar to Phillips, but the only difference is that it features a pointed 75° V shape.

It is superior to Phillips drive in one way, as its bit can fit all screw sizes. It is mostly found in marine hardware and needs a specialized screw driver under the same name. Its tool recess features sharp cross, thereby enabling higher torque to be applied, unlike the rounded Phillips head type.

Hexalobular socket

Hexaloboular Socket screw Head


The hexalobular socket screw driver, which is rather popular as Torx and star drive, is a star-shaped recess as the name suggests, featuring 6 rounded points.

It is specially designed to allow higher torque transfer from the driver to the bit, as compared to other drives. The Torx is mostly used in electronics and automotive industry, as it is highly resistant to cam-out and even reduces the need to go down with the drive tool.

Torax Screw Head


Brass Wood Screws: Preventing Cracks While Fastening Wooden Panels

Earlier when the concept of brass wood screws was not conceived, the cabinet makers used to manage with nails, glue and wooden peg, so as to fasten the wooden panels. Although the glue can fix the panels, it is not sturdy enough for a longish time period. A wooden peg is however better than the glue. You need to carve a hole for it and nails, on the other hand used to be the perfect option during those times. They keep the furniture pieces intact, but again they even feature some flaws, like there are chances of bearing a crack on the wooden surface.

Brass Wood Screws

The hardware industry came up with an advanced option to deal with such issues. The wooden fasteners have now become a favoured option as these do not mar the beauty of the furniture by making a crack on it. Such kind of fastener is quite popular these days because of its advanced features and ability to safely fasten the panel in place. The market is today flooded with several types of wooden screws and you may be confused in choosing the particular model, best suiting your requirement.

Basic factors to understand the brass wood screws:

1. Such screws feature two types of heads, which include the flathead or slotted type and the Phillips or cross head type. The Mutual Screw and Supply is a leading web store, dealing with such kind of hardware supplies. The latest additions in their product page include the square head Phillips and the simple square head type.

2. Such kind of wooden fasteners also feature various head shapes, such as the round head type, which features protruding top with broad bottoms. Another kind is the flat head type, which is ideal for installing hinges. The hinges can be sunk deep into the wooden surface with its help. The last but not the least is the oval head type, which is both rounded and flat type.

3. Such kinds of screws are usually made up of hard steel, which comprises of brass and stainless steel materials.

You can even go for coasted brass wood screws to prevent corrosion.
