28 Different Types of Fasteners

This article will learn about some of the different types of fasteners available. But before that, let’s discuss what a fastener is.

What is a fastener?

The word ‘fastener’ is a broad term that refers to various tools. Screws, bolts, nuts, and other similar tools have the same goal.

The goal is to allow items to adhere mechanically. Fasteners are mechanical devices that hold things in place or together.

You may, however, argue that glue is capable of doing this purpose. What is a fastener if the bond is not an example? This will cause us to elaborate on the original definition. Hardware fasteners are mechanical fasteners that keep items together.

Furthermore, Fasteners are divided into several categories. ALSO, It divides them into two categories: permanent and non-permanent fasteners.

Fasteners are often thought to establish non-permanent joins. For example, two components joined by a fastener should be able to be separated.

The components must not be damaged when they are separated. The rivet, a permanent fastener, is an exception to this rule.

However, the fact that most fasteners create non-permanent joints does not imply that the joint is weak. Using fasteners with suitably shaped threads will ensure that your things are securely fastened.

Also, you can be confident that your item can withstand a lot of stress this way. They are highly adaptable, making them suitable for many joints.

Types Of Fasteners

Hex-Head Bolt

The head of this bolt is hexagonal in shape. The six sides of the bolt provide to provide an appropriate variety of angles from which to approach the bolt.

This is especially critical when You must fasten the bolt to a difficult-to-reach location. These bolts are widely utilized in machining because they are simple to assemble and disassemble.

Double End Bolt

This bolt appears to be a threaded rod. On the other hand, a double-ended bolt has a thread on both ends. As a result, they can work with a nut on one or both ends.

Eye Bolt

A loop on one end and a thread on the other define an eye bolt. The machine’s size and design determine the loop’s performance. This is one of the different types of fasteners.

Carriage Bolt

Bolts with convex metalheads, square necks, and threads are included. They are used to secure wood items. It simply fits into a square neck into wood pieces by exerting pressure. Also, they have self-locking potential as a result.

Socket Head Bolt

Some people may refer to these bolts as Allen bolts. They have hexagonal perforations and cylindrical heads. You can tighten this bolt with an Allen wrench.

Cap Nut

They are dome-shaped with closed ends. This contributes to the protection of the bolt-nut connection. It also ensures that your work has an excellent finish.

Castle Nut

One of the ends of these nuts has a notch. You can insert pins through the notches in their design. Also, they work well in situations when low torque is required. This is one of the different types of fasteners.

Weld Nut

Weld nuts are used to secure components in difficult-to-reach places. You must weld them to the part’s surface.

Hex Nut

The most prevalent type is hex nuts. They’re inexpensive and straightforward to put together with a wrench.

Self Drilling Screw

They develop internal threads during installation and are also known as self-tapping screws. From tip to head, the shafts are entirely threaded.

During turning, these screws quickly create niches for themselves in the component. However, The architecture of screws and bolts are similar.

Their male threads begin at the very tip. Their heads can also be in a variety of forms. There are a few distinctions between bolts and screws, though.

Screws frequently require internal threads to hold items together. On the other hand, Bolts can retain grip between non-threaded pieces and nuts.

Sheet Metal Screw

The cutting threads on these screws are highly sharp. This makes it easier for them to cut sheet metal, wood, and plastics. Their shanks are fully threaded and include a notched point for chip removal.

Machine Screw

Screws are utilized in almost all machines. They have a similar structure to sheet metal screws. They’re inserted into holes that have already been drilled. As a result, there’s no need to drill a hole for installation.

Hex Lag Screw

These are big screws for wood. They are beneficial in heavy-duty machinery and wood activities.

Deck Screw

These screws are designed to be easily installed into deck and wood surfaces. The bugle head and square drive help to eliminate stripping effects. Furthermore, this is one of the different types of fasteners.

Wood Screw

Partially threaded wood screws feature smooth shanks. They glide effortlessly through wood and bring the planks together.

Plain Washer

These washers are used to keep components separate from nuts and bolts. They aid in the preservation of surface coatings. They also increase the surface area of the material, spreading the load.

In addition, Washers are fasteners used in conjunction with nuts and bolts. Also, they’re commonly found beneath joints, bolts, and axle bearings.

Also, Washers serve a variety of purposes, including reducing friction. They also aid in eliminating leaks and the isolation of various components.

The use of a washer will assist prevent component loosening due to vibration. The washer is one of the different types of fasteners.

Spring Washer

Their circular shape has been altered slightly. They behave like springs, and their flexibility increases the elasticity of joints.

Locking Washer

Even when friction or vibration, they keep nuts and bolts in place. Most users of spring washers prefer them.

Dock Washer

These are heavy-duty washers that aid in the construction of docks. They’re also handy in heavy-duty construction where thick washers are required. This is one of the different types of fasteners.

POP Rivet

These tubular rivets have a cap and a mandrel on them. They can be countersunk, open-end, or closed-end.

In addition, Permanent fasteners like rivets are the most common. They aid in securing a variety of materials and provide resistance to shearing force.

A rivet is very light. It also has a head at each end to help support axial loads. Rivet guns are used to secure components with rivets.

Threads are not required for rivet installation. They are preferred in the aerospace sector because they are simple to inspect.

Multi-Grip Rivet

Multi-grip rivets are best used when the thickness of the mounting materials varies. The rivets may grow to the desired size and secure the components.

Tri-Fold Rivet

There are three cuts in the hats of these exploding rivets. The cap folds outwards for increased strength and maneuverability.

Large Flange Rivet

The hats of these rivets have bigger washers. They aid in the quick and effective connecting of materials.

Anchor

Anchors are fasteners that work similarly to a boat’s anchor, which is inserted into the seabed to keep the ship from moving. It’s usually used to secure anything to a surface like drywall or concrete.

Also, they embed themselves in the material and hold the object you’re attaching in place. Anchor is one of the different types of fasteners.

Nails

It’s a bit metal spike with a broad flat head that’s driven into the wood and used as a hook or to hold items together. Nails have been around since the beginning of time and have now become a common household item.

However, Because a nail does not have threading on its body, you can quickly tell the difference between a screw and a nail.

The names of the various types of nails are derived from their applications, which might assist you in selecting the appropriate nail for the job at hand.

Retaining Rings

Retaining rings are fasteners that are used to secure shafts or components. They frequently create designs in various shapes. They’re used in a variety of machinery applications.

A retaining ring, such as this one, is used to keep the latch pin of an IC engine piston in place. It’s also utilized in the high-pressure fuel pump of a diesel generator to keep the assembly together.

Most retaining rings are used once and then replaced when the machinery is fixed, although You can reuse some.

In conclusion, any of the different types of fasteners you employ will always be determined by the needs of your application. Consider whether your fastener will fit.

The fastener’s design can significantly impact how much torque it can take. To hold numerous components of your parts, you may need an extremely long flange bolt.
