Making of Drop Forged Eye Bolts

The drop forged eye bolts are 316 stainless steel type fasteners and are usually available in 1/4″ x 2″ size. Although there are other sizes available in the market, eye bolts shown here are supplied standard rivets enabled flaunting a hot galvanized finish.

Drop forged eye Bolt

Before being galvanized, these are threaded national course and are equipped with hex nuts, which are tapped oversize to render easy galvanizing thickness. Not to mention, these rivets are usually without a shoulder and are also available along-with special shank and customized thread sizes.

Loads applied on drop forged eye bolts are usually based on a safety factor ranging from 5 to 1. When tested, these particular eye bolts get pulled with a direct tension at a uniform rate of speed. Any aberrations such as shock loads, angular lifts, modifications of the basic forging etc. result in dramatically reduced maximum loads.

Process

The drop forging is a type of metalwork process, which helps in gradually shaping a heated piece of metal, known as ingot. This technique involves creation of ingot, by giving repeated blows from a hammer or a die. This is done by raising and then dropping the hammer on the metal piece, thereby either flattening it or molding it to a desired shape.

Special shank, Thread Lengths and other sizes of Eye bolts

Determining the intricacy of the required design, the procedure sometimes involves numerous dies and other steps as well.

The drop forged eye bolts are usually produced with a close approximation of the finished metal piece. In some cases, some additional method, such as machining is involved, so as to obtain the required tolerance. It is a type of manufacturing process, which is used to create objects out of metal.

Shoulder Pattern Type Drop Forged Eye Bolts

The drop forged eye bolts are used extensively in the automotive industry in producing various engine parts, gears and axles.

The dies used in this method are typically made up of high alloy steel known as tool steel. Such dies are designed specifically to become resistant to daily wear and tear. These are also capable of withstanding repetitive rapid heating and cooling cycles.

Forged Eye Bolts Recommended Load Limits

The dies used in this technique are made into two halves. While the upper half, known as hammer, is fastened to the raised block, that is dropped into the ingot; the lower half, known as anvil, is a rather stationary die used against the ingot, that is forged.

Another commonly used drop forging method is the open-die type. In this method, the dies do not completely encircles the work-piece. This kind of die is usually flat unlike contoured dies and cutting dies and are far more superior than the normal dies.

Open Die type Drop Forging method

This kind of open design accounts room for the expansion of the ingot, when it is hammered to the desired thickness.

The drop forged eye bolts are also prepared under various other techniques such as cogging and edging, impression-die forging and closed-die forging known as flash-less forging.

These rivets, which are available in steel and C-1023 type, are usually supplied standard fasteners featuring a hot galvanized finish.

Steel drop forged Eye Bolt

Before being exposed to galvanizing, they are threaded and enabled with hex nuts tapped unshapely, which assist in galvanizing thickness. Special shank and thread sizes for these rivets are also available in the market. As per your requirements, you can choose accordingly.

For these fasteners, loads are applied on a safety factor from 5 to 1. When tested, all such eye bolts are easily pulled at a uniform rate of speed in a direct tension. However, be warned that any kind of deviations, including shock loads, angular lifts, modifications of the basic forging etc. will result in dramatically reduced maximum loads.

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

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.

Slotted

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

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

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

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

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

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

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.

Few Tips Help Buy Accurate Metric Tap Bolts

Machines as well as components, which are joined with screws and bolts, feature distinct torque specifications. Fasteners, such as metric tap bolts, are manufactured specifically to go through a nut/hole, which is pre-tapped to create a mating thread for that fastener. These rivets are designed to be conveniently used by any pneumatic tools or a wrench.

Metric Tap Bolt

How to identify metric tap bolts

People looking for these types of bolts may easily get confused with the American bolts. They are quite different in the measuring technique. While American bolts use the number of threads/inch as a measurement, the metric bolts use the distance between the threads.

Metric Bolts marked with Numbers to Indicate their Relative strength

These bolts are normally measured in millimeters as the standard reporting unit.

How to measure

The shank diameter of this bolt should be measured first, which is the distance from one side of the bolt to the other through the center

Metric grade to SAE grade Comparison

The number of threads should now be counted. Now the distance should be divided by the number of threads. For instance, if 10 threads make one centimeter, the thread length should be of 1 mm

The length of the bolt should be measured i.e. from the start of the head to the end of the bolt

Metric tap Bolt and Nut Technical Specifications

Now note the reading as such – diameter x distance between threads x length. For e.g. if a bolt has diameter of 2 cm, 1 mm between the threads and length of 25 mm then it would read as “2x1x25”

Torque Specifications

Like other fasteners, the metric tap bolts are also enabled with torque specifications. The torque refers to the total amount of force, which is required to turn the nut and bolt around a fixed point.

Internal and External Thread Graph of Metric tap Bolt

In the metric system, bolts are usually expressed as per their diameter, the distance between their threads. For e.g. a fastener with a size of 12×1.75×30 suggests that the fastener is 12 mm in diameter with a length of 30 mm and 1.75 mm of distance between the threads.

In the metric nuts, these bolts are categorized under various grades. However, the metric nuts do not have any identification marks and are rather listed by thread spacing and diameter.

Different Heads and Sizes of Metric tap Bolts

Low Grade Specification

A low grade 6 mm metric tap bolt features maximum torque values ranging between 3 to 5 foot-pounds. Similarly, a 8 mm bolt will feature torque ranging between 8 and 12 foot-pounds. And a 10 mm metric bolts will feature torque between 15 and 22 foot-pounds.

8.8 Grade mark Metric Hex Bolt

8.8 Grade Specification

A 14 mm metric tap bolt with a grade of 8.8 will require 101 foot-pounds of torque. A 16 mm of bolt will require 146 foot-pounds of torque. An 18 mm bolt requires 201 foot-pounds of torque and a 20 mm bolt requires 285 foot-pounds of torque.

Typical ISO bolt and nut Markings

FYI: The bolt torques are flexible and depends heavily on the lubrication of the bolt. The above mentioned specifications are for dry and unlubed metric bolts.

Dimensions of metric tap bolts

Shank

The shank or the threaded portion of the bolt is defined by the size. The shank’s diameter is usually used as the primary measurement. the length of the shank varies greatly with the width. Those two measurements are determined by suppliers like Mutual screw, to help customers identify the metric tap bolts.

Internal and external thread graph and specifications of Metric bolts

An M10x20 metric bolt is enabled with a 10 mm shank which is 20 cm long.

Head

The diameter between the flat sections of the head is always 1.8 times more than the diameter of the shank. An M10 metric bolt with a 10 mm of shank will have a 16 mm of hex head. the shank size can be calculated by measuring the head’s dimension and dividing it by 1.8.

Specification Requirements of Metric Tap Bolts

How to buy metric tap bolts

These bolts are usually sold based on their length, width, thread size and diameter. Some of these rivets are also labeled as per their strength. In our store, these items are sold as per their size and coarse thread.

Before purchasing these rivets, always make sure your measurements are in metric units.

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.

Glider Bearings: Essential for Building a Rocker Chair

Planning to construct a rocker? Then you’ll surely need some suitable glider bearings. This particular hardware kit is an essential necessity for building any type of glider, be it wooden, net or anything kind of material. If you’re planning to spend your winter vacation in any national park and your family is keen in camping then I highly suggest you to carry such type of kit.

Glider Bearings

With this help, you can easily hang a net bed between two trees or can easily carry your rocker chair to the woods. In order to build a rocker, you’ll have to make a hole of around 1-1/8 inches for the bearings to get easily fitted in. You should always use hardwoods. The nuts, bolts and washers should be of 3/8 inches. The screws must feature #6 square recess drives. In this way, you can build up a simple arrangement as used by the professional manufacturers.

Even if you’re not going into the woods, you may be thinking of implementing a net hanging bed in your courtyard. It will be quite expensive in calling down a professional carpenter for this simple job. Instead, you can volunteer to do fix this job. All you need is an appropriate place and required amenities. And with the availability of accurate glider bearings, you can hang your gliding bed on your own.

You can take the help of the Internet. These days, almost every other item, be it apparel, gift or any hardware supply can be easily fetched online. Such tiny essentials are also available online.

Besides, manufacturers of rocker chairs also rely upon this company and order items on bulk amounts. With the minimal shipping charge, you can easily avail your item in a cost-effective way.

The glider bearings are unique hangers, featuring ball bearings at both ends. They give your glider projects an ultra-smooth, back-and-forth action. These are made up of rust resistant steel and usually measure 7-1/2″ between centers and have a 1-1/4″ offset.

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.

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.

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.
