The brass socket is a type of head cap screw, which features a hexagonal raised drive and is specially designed to measure the certain amount of tensile stress of any object, which can withstand any kind of wear and tear. It is made up a stronger alloy component of steel as compared to regular screws. But these fasteners vary the composition, as they are available in various grades in various companies. These are usually fastened by using a slot wrench and feature various types of heads.

While some feature cylindrical head, others feature a button or flat head. The flat head types are specially designed to fi into the countersunk holes. These cap screws are most commonly used among all other fasteners in industrial sectors, because of their economical, durable and safety features.

How Ledgerlok Screws are Better than Lag Screws

Ledgerlok screw is the first wooden screw, specially designed to attach a deck ledger board to the rim stud of a house and not to mention, it requires no pre-drilling like normal lag screws.

Ledgerlock screws

This structural screw is easy to install, as it is coated with a three-step coating process which prevents corrosion. The screw is furthermore, capable of preventing corrosion even in pressure treated wood and it is ACQ approved.

To facilitate more, the fastener is enabled with a built-in washer head, which eliminates the necessity for an additional washer. Such kind of advanced fastener is indeed time as well as money saving investment. The screw’s huge hex-head enables for greater bit engagement, hence reducing cam-out.

Shape Description of Ledgerlock screw

Soon after the launch of this code-approved deck ledger board fastener, it became a huge hit specially over lag screws and through-bolts.

Installation Procedure

The ledgerlok screws should be installed by using a high level torque and drill bit of 1/2″ variable speed (at least 18V if cordless).The user needs to carefully choose the length of such fasteners, so as to completely engage the threads on the main part i.e. rim joist. Now washer flush should be brought to side member, but make sure not to countersink it.

An Insight into Our Galvanized U Bolts

As the name suggests, U bolt looks like the letter U, featuring two threaded arms suspending from a curved base. It is available in numerous sizes and features various applications and uses.

The galvanized U bolts undergo a chemical process to protect themselves from corroding and rusting. Such fasteners get coated in layers with ZnO (Zinc Oxide). This kind of coating prevents these metal pieces from getting corroded. Besides, the coating renders a longer life to the rivets, durability to withstand wear & tear and a glossy finish, thereby making them attractive.

In simple words, galvanized U bolt is a rod, being threaded at both ends and bent to form a ‘U’ shape. These types of bolts are usually found with a smooth curve, specially designed to accommodate a cylinder; for instance, the axle or exhaust tubing.


There are certain U bolts featuring a squared off shape, are specially manufactured to fasten flat bases such as wooden blocks, square tubing or any other kind of flat layers. Sometimes, the ends of the bolts feature a bar/crossed member drilled with holes, which slide over the open ends to enclose them.

Sometimes, the ends of the bolts feature a bar/crossed member drilled with holes, which slide over the open ends to enclose them.

Keeping a few pieces of galvanized U bolts around the house can be useful for home owners who are planning to go for home renovation projects, as these coated rivets are versatile enough to match various applications and also helpful in surprise settings.

At Mutual Screw and Supply, we offer both hot dipped galvanized U bolts as well as stainless steel U bolts, to satisfy varied industry requirements. Click here to know more.

These types of bolts are designed to meet an extensive range of applications, including domestic, commercial, construction, marine, off-shore, automobiles and various other industry requirements. We offer these metal pieces in various configurations, materials and gages so as to meet those above mentioned requirements.


Like in automobiles, our hot dipped galvanized U bolts are used in numerous applications. For instance, they are used to attach springs to the rear axles and front of the heavy-duty trucks, off-road trucks and cars. These fasteners are used to attach truck parts to the frames and are used in ringing applications and anything which requires a clamping force between two pieces.

These fasteners are used to attach truck parts to the frames and are used in ringing applications and anything which requires a clamping force between two pieces.

The U-shape of these rivets help them keep firmly in desired position, thereby preventing the object to easily get pulled away from its fittings. This further leads to inducing durability and safety.

Apart from stainless steel and galvanized pieces, we also deal with steel zinc plated, aluminum, black oxide, plain finish etc.


The threaded ends of the galvanized U bolts are designed to get along with screws and washers. Some people are also seen using a cross-piece, spanning both the ends so as to make the fastener secure in particular settings and applications.

Like other bolts, these pieces are also manufactured to get into any pre-drilled or pilot holes. The U bolts are most commonly used in fastening various pieces to beams and poles, mostly in houses. These pieces help in suspending any object from the utility pole. In such cases, the U bolts are used along-with cross-pieces which snag the bolt in place.


Besides our bolts are also used to pass cables across the walls. While both the ends are inserted into the walls, the U face holds the cables or any other flat materials against the wall.

However, depending upon the type of application, the size and grade of the bolt should be chosen, in order to eliminate any work-arounds later. And if you are willing to use them in corrosive or humid environment then our hot dipped galvanized U bolts work best for you.

Particle Board Screws: Idea for Installing Soft Wooden Floors

Particle board is a composite wood, made up of a combination of wood chips, such as sawmill shavings, synthetic resin, any suitable binder, wooden chips and saw dust. It is also known as ‘clip board’ and is the engineered wood, as it is not naturally extracted from trees. For such kind of furniture, special kinds of fastener known as particle board screws are used.

Particle board screws

Considering various requirements, the hardware supply industry offers different types of screws. So, it’s always crucial to know what the exact type of screw, which best suits your requirement. As in the case of the clipboard – if you use any other screw then you may easily end up damaging the surface of the board. After considering the type, it is now required to know the exact size.

The adhesive present in the chipboard is usually a kind of resin that is adhered together with wooden chips to create boards of different density. Although chip board’s high density factor is quite strong, still it is known as ‘soft wood’ and is less permeable to moisture. This kind of artificial wood is lot cheaper than the natural furniture and this is the major reason for its popularity. While natural wood’s price is soaring high these days, you can easily fetch the engineered wood at quite cheaper rates, plus it has distinct advantages as compared to the normal one.

These days it is also used for flooring in kitchen and cabinets and it is easily deceived because of the coating of the melamine. And for the installation process, the particle board screws are definitely required. Such types of fasteners are thus heavily used in the interior works and are now most frequently bought on bulk amounts.

If you go online, you would be bombarded with an array of web stores dealing with such items. You may get confused, so let’s help you with this. The Mutual Screw and Supply is a well-known fastener company, who can help you fetch your desired stuff at quite affordable rates.

Thread Rolling Screws: Helping Bolts Impress into the Raw Stock

The self-tapping or thread-rolling screws are those types of fasteners, which feature threads, specially designed to tap in their own holes. Such types of rivets are ideal for fastening objects in softer materials such as plastic and wood, but do not suit at all for harder materials such as metal.

Thread rolling is a type of fastening procedure, which involves penetrating bolts threads into the raw stock instead of cutting them. This procedure requires a sturdy steel tool to be formed in the shape of the necessary thread. The raw and uneven stock is spun at a definite rate; simultaneously the tool bit is pressed against it with high pressure. Thus, the shape of the screw thread is efficiently placed upon the stock base.

The tool bit is constantly put under pressure and is moved towards the stock, till the full-depth threads are created. The thread forming process is bit cheaper as compared to the thread cutting, thereby yielding durable and safer end results.   Fasteners, such as screws, nuts and bolts are the most commonly used rivets in the world, with ample quantities produced across the world every year. These rivets are generally yielded from raw metal stock, which is created prior to the introduction of threads. Basically, there are two steps involved in forming the threads; thread rolling and thread cutting.

The thread cutting procedure involves a cutting die, which is moved up the length of the rotating stock, thereby cutting away the metal surface to create the threads. Although this process is effective, it is always time-consuming.

The thread rolling screws on the other hand is a better application in various aspects. In this method, a sturdy tool bit is used to insert the threads into the stock surface. The tool bit is formed in the shape of the threads and with great pressure; it is then forced against the stock.

Basic Difference between Metal Screws and Wood Screws

Fasteners such as screws are extensively used in hardware industries and they are available in huge varieties and patterns, so as to meet various industry requirements. Many people carry a notion that screws are all the same. But if you visit any online hardware supply store, such as Mutual Screw and Supply, you would learn that these fasteners are available in various designs and each one of them features distinct functionality.

You can only settle down for a particular hardware item, which meets your requirement, provided you understand the basic difference between various screws, say metal screws vs wood screws. Many people would assume that the basic difference lies in their materials. But this is not entirely true, as the metal rivets can also be used in wooden and fiber glass surfaces and the wood fasteners can also be used in surfaces other than furniture. However, their main difference lies in their features and designs.


You can site a major difference in their threading pattern. These two rivets are threaded differently. While the sheet metal fasteners are benumbed and are threaded on the entire body, the wooden rivets are comparatively soft and feature a tapered shank. The threading on metal ones is available up to 3 inches and the wooden ones feature threading up to 1 inch. The sheet metal screws flaunt a straight shank along-with a finer threading pattern other than the wooden rivets, which are threaded only two-thirds of the way up.


Pitch refers to the number of threads per inch. The metal rivets feature number of pitches than the wooden ones, which indicates that they feature a coarser pitch. In case of the wooden screws, the top portion is often not threaded, thereby enabling the rivet to be popped up from the surface.


The metal fasteners can also be used in furniture pieces, whereas wooden screws are not ideal to be used in metal surfaces. The metal screws are ideal for self-tapping. (Self-tapping means that the fastener can create its own threading as it advances through the material). These self-tapped rivets are used in plastics, fiber-glass and plywood, whereas in wooden screws, self-tapping is not possible. These fasteners are used in outdoor building structures such as decks and fences.

Sex Screws: Highly in Demand for Their Low Profile Knurling Features

sex screw, which is also known as barrel nut or barrel bolt and even Chicago screw at times, is a type of fastener that features a barrel shaped nozzle and a protruding boss, which is threaded internally (a boss is basically an extended feature on a work piece).

This protruding feature is placed within the components, which need to be fastened, while the rivet’s flange enables the bearing surface.

Chicago ScrewThe barrel nut and its accompanying machine screw enables flush on both sides of the surface, which are tightened. Such kinds of bolts are much in demand, most probably because of their low profile as compared to other bolts.

The Chicago screw usually possesses a built-in feature, like a slot, which helps in securing any fastener.

Sex screws are used in bolting applications, mostly in situation which demand to have a head on both sides of the joint. The sex bolt is enabled with a female thread, thereby enabling it to meet with the bottom of a standard bolt and connect.

There are some sex bolts, which are also known as architectural bolts and feature knurled cylindrical containers. Knurling is commonly a manufacturing terminology, used when a process is typically carried out on a lathe and a diamond shape pattern is cut into metal.

Such kind of rivets are also used in binding posts, which are quite similar to architectural bolts, because of their special designs, which are fashioned to be assembled from one side. in addition to, they have also got teeth on the flanged base, which are helpful in fastening.

Stainless steel sex boltsThese metal pieces were originally produced for the printing industry, so as to bind huge catalogs together. But now, with their multi-faceted features, they are also used in numerous other ways.

The stainless steel sex screws usually feature combo truss head, which are usually broad with a low profile rounded cap. These are a combination of rivets, which feature both slot as well as X shaped cells for use and can be easily used by a Phillips head or flat bladed screw driver.

The Chicago screws can be easily fetched online. The Mutual Screw and Supply is an ideal destination to look for all sorts of fasteners. Browse through the product page to find more!

Only Your Thumb is Sufficient to Fasten the Thumb Screws

A thumb screw a kind of fastener, which features an over-sized head with a diamond-shaped or knurled anchor finish along-with large wing like blades, thereby enabling the screw to be used as per the requirement.

Thumb screw

Such kind of rivet is used in applications, where any object may need frequent re-installations, as it is in the case of the safety cover or in case of various electronic devices. In such cases, such kind of fastener makes it possible for you to easily remove it by just twisting it with your thumb and forefinger.

In most of the application, the thumb screw is used as a bolt. While a screw by nature is usually pointed in shape and is used to develop its own threads when inserted into sheet metal or wood, the thumb screw features a blunt-nosed bolt, which is tightened into any threaded hole. The basic advantage is that it renders easy installation and removal processes without any help of tools, as it is with the case of other screws.

A Thumb Screw Side View

The battery cover and other certain electronic devices use such kind of rivet. You would have often heard that the thumb screw is captured – it means that bolt of this rivet once loosened, it won’t fall out of the cover. This particular rivet uses a washer, which is set in place to sustain the metal piece in the cover. This is a handy hardware supply, thereby preventing the locking screw from getting lost.

It is available in various designs, which incorporate a Phillips or flat screwdriver into the fastener. This helps the rivet to be easily fastened by a wrench even and if not then it can be still tightened by finger. In heavy-duty applications, such as in boats and off-road vehicles, it is highly recommended because of its tendency to get loosened over time. In case of the fasteners, featuring knurled heads, it is possible to attach the screw with a pair of pilers, so as to ensure accurate torque implementation.

Different Types of Screws and their Uses

Before elaborating the different types of screws available today in the market, let us first of all have a quick review on its definition.

So what is a screw?

A screw/bolt is a type of fastener distinguished by a circular ridge, known as threads which are wrapped around a cylinder.

While some screw threads are designed to get along with an internal thread, also known as complementary thread, there are some threads, which are fashioned to cut a helical groove in a softer material, say wood or plywood, when the fastener is inserted. The major function of a screw is to hold two objects together.

These kinds of fasteners are astonishingly versatile and powerful enough to be hold two different surfaces intact. The basic concept behind such metal objects’ functionality is their threaded cylindrical parts, which are designed to get inserted into any kind of material, be it a plastic, wood, metal or plywood. However, there are various types of screws available suitable for distinct surfaces.

These types can be distinguished depending upon the driving methods, job requirement, head shape, type of threads and material used to make such metal pieces. Have a look!

Driving Methods

Slotted: The heads of such fasteners are most probably the most ancient and commonly used variety. The linear slot in the screw’s head is easily gets along-with any standard screw driver, such as the flat-head screwdriver.

Phillips: These are the enhanced forms of slotted ones. Their cross-shaped laps, which are not continuous up to the edge, will certainly require a Phillips-head screwdriver. The heads of such rivets, featuring a circular shape, enables a larger mating surface, thereby reducing the chances of wear and tear. Plus, they also prevent the chances of slipping. A cross head usually features 2 full-length slots, which can only work with a flat-head screwdriver.

Square: This type is also known as Robertson screw head and features a square dent to reduce the chances of slipping. It requires a special kind of driver for its usage.

Hex: This is again available in two designs. Such types of fasteners either feature a hexagonal recession in the head or do not have grooves at all. The hex socket screw/Allen screw requires an Allen wrench, featuring a hexagonal shaft and the other type of hex screw’s head is completely hexagonal in shape. A socket wrench is required to tighten or loosen it.

Apart from being available in above mentioned types, the screws are also available in various materials. While some are made up of steel and stainless steel, there are fasteners, which are made up of brass, nylon, aluminium and are also available with zinc and black-oxide coating.

Finding a Suitable Tool for Stud Screws

Someone has gifted you an exquisite artwork this New Year, or maybe you would have won a high-quality wooden shelf in a lucky draw.

Stud Screw manufacturing station

Now the attempt to fix it begins. The question is how to hang those things? Either high or low and not to mention it may also be the raunchy lopsided? You have to struggle hard with the correct size of screws, after you’ve driven some foot-into-mouth fasteners into the wall the wrong way before you get some suitable pieces.

Earlier hanging pictures, mirrors and artworks was so much complicated because of the dearth of right kind of tools and supplies at the nearby store, for which you’d to depend upon professional craftsman even for petty jobs. But with the recent revolution in the hardware industry and with the advent of the online dealings, such manual jobs have been simplified to a much greater extent as soon as low-cost tools and a huge range fasteners such as stud screws hit the market.

Stud screw on a Dry wall

You can kick-start with some stud screws and a stud finder, which would cost you arround $10. If it’s a huge and heavy mirror or a wooden shelf or something very fragile, you’ll have to definitely go for this paricular type of fastener and tool, as you may have to insert screws or picture bolts into the wooden studs that are 16 inches apart behind your drywall.

Suh kind of method is also tricky, as you can hide the studs by rapping on the wall.

When you move the screw finder across the wall, you would see some light flashing out along-with a beep sound and this indicates that you’ve reached a stud. As wood is thicker than the half-inch drywall, so you can easily detect the hidden fasteners. After this, you can now mark the spot with a pencil or else leave upto your tool, which would make a tiny pinhole to help you locate the spot.

Different types of screws

In states like Arizona, homeowners face a much more complicated issue, as they live in block masonry homes, whose walls are made up of concrete blocks.

In this region, usually builders insert “furring strips” (wooden strips) measuring about 1 inch on top of the concrete blocks and then fasten the drywall to the wooden strips, which are 16″ apart. The above mentioned tool is even ideal for finding these in-built strips as well.

Stud screw to fix furring strips

Besides stud screw finder, you can also go for laser level. This advanced tool is available for just $20 or less, which projects a beam of red light across a wall, which furtehr enables you to line up the stud screws to hang up your gifted artwork or the heavy mirror.

Another effective toll is the power screwdriver, through which you can easily drill stud screws into studs. You can even go for a power drill, which can also speed up things up, especially in cases if you’re using molly bolts or toggle bolts on drywall.
