Beginners guide to fasteners

fasteners australia

Fasteners are mechanical components that join two or more objects together. Fasteners may be used to attach permanently or temporarily, depending on the conditions on the job site. There are many different sorts of fasteners to be aware of, each with a different purpose. Also, you can easily find fasteners Australia wide from any supplier as they are readily available. 

Types of Fasteners

  1. Threaded Fasteners
  2. Nuts
  3. Washers
  4. Rivets

A) Threaded Fasteners:

These are the most popular fasteners, which are mostly used for constructing components that can be installed or removed as needed. Bolts, screws, and studs are the three most often used threaded fasteners. Let’s take a closer look at each of them.

1. Bolts: 

Bolts have a head on one end, typically a hex head, and are threaded on the other. To hold the material in place, these are normally used in conjunction with a nut or a washer.

2. Screws: 

Screws are similar to bolts in that they both have a head on one end and a thread on the other. Screws are used to screw into a threaded hole, which is the fundamental distinction. Cap screws, machine screws, wood screws, and other types of screws might be utilised depending on the site’s requirements. 

3. Studs: 

Studs are distinguished from bolts and screws by the fact that they are threaded on both ends and hence lack a head. Internally threaded holes are compiled together with this component.

Nuts

Nuts and bolts are used to connect two or more mechanical pieces. The hexagonal nut is the most well-known, although there are many other types of nuts that are employed depending on the needs of the site.

1. Hex Nuts

An internal thread runs through hexagonal nuts. These are the most common nuts, and they’re employed in practically every industry for a variety of purposes.

2. Lock Nuts

Lock nuts are used to secure a nut in place without the need of a clamp.

3. Nylon Insert Nuts

These nuts, also known as nylon nuts, have a nylon insert that prevents the nut from loosening due to vibration.

4. Shear Nuts

Shear nuts have a hexagonal gripping point that snaps off during maximum torque, leaving only the nut to remove, which is difficult.

5. Wing Nuts

Wing nuts are typically employed in applications that need the nut to be removed repeatedly. These nuts have two external “wings shaped faces” that make manual rotation a breeze.

Washers:

Washers are the components that go between the head of a bolt, screw, or nut and the material being clamped. The primary purpose of a washer is to improve the head’s bearing area while simultaneously protecting the material from harm. Washers come in a variety of shapes and sizes, each with its own set of applications and functions.

1. Flat Washers

The most common type of washer is a flat washer, which is used to evenly disperse the load of a bolt, screw, or nut.

2. Spring Washers

Spring washers, also known as locking washers, are used to prevent a bolt, screw, or nut from loosening due to vibration.

3. Cup Washers

Cup washers are typically used in conjunction with a wood screw, depending on the site’s requirements.

4. Repair Washers

Penny or Fender Washers are the most common names for these washers. These washers contain a small hole in the centre and are meant to provide a larger bearing surface to avoid pull-through.
