What are Fasteners? Why do we use them?

Fasteners are tools, some small, some big, used to fasten anything securely in one place. Fasteners include a wide variety of tools, all of which perform different sorts of functions and are used to serve various purposes. The basic use of each fastener is to mechanically hold things together firmly. Fasteners join two objects, parts, or anything together without damaging them. If you ever remove a fastener from its place, you will see that it held things together without damaging any of them. Therefore, when you remove the fastener from two joined objects to separate them, they separate very easily and become two separate objects as if they were never together. Well, the types of fastening all the fasteners can do are three. As follows:

Types of Fastening:

·         Temporary Fastening:

This type of fastening is done as such that when the fasteners are removed, the objects are disjointed very easily.

·         Semi-Permanent Fastening:

This type of fastening is semi-permanent in the sense that it can be removed partially to disjoint the objects, but it may get damaged while disjointing.

·         Permanent Fastening:

This is a type of fastening that is almost like as if you have welded two objects together; this fastening will never come off, and the joined objects can never be disjointed with getting damaged. 

Materials of Fasteners:

Fasteners come in a variety of different materials, all of which give different strengths to a fastener. A China fastener exporter can assist you with fasteners of all high-grade premium quality materials. The materials available in every fastener are Steel, Stainless steel, Carbon steel, Zinc plated steel, Brass, Alloy steel, Monel, Aluminum bronze, Silicon bronze, Mild steel, Hardened steel, Glass-filled polymer, Inconel, Zamak, Nimonic, Titanium, Copper, Nickel and much more. 

Types of Threaded fasteners:

Threaded fasteners have threads on their internal and external side. The threads on these fasteners make them very easy to install and form a temporary fastening. Types of threaded fasteners include:

Ø  Bolts and Screws:

Bolts and Screws are almost similar to each other. They have a head on one side and threads on the other side. The only difference is that screws are used in a threaded hole, and bolts are used with nuts or washers.

·         Carriage Bolts

·         Eye Bolts

·         U-Bolts

·         Wood Screws

·         Machine screws

·         Self-Tapping Screws

·         Socket Screws

·         Grub Screws

Ø  Nuts:

Nuts are round and are threaded from the inner side. These are always used in combination with bolts.

·         Hex Nuts 

·         Lock Nuts

·         Nylon Insert Nuts

·         Shear Nuts

·         Wing Nuts

Ø  Washers:

These are not threaded from any side and are round in shape. These are used in combination with a nut, bolt, or screw and are placed between these and the surface. They make the bearing stronger and help not to damage the object.

·         Flat Washers

·         Spring Washers

·         Cup Washers

·         Repair Washers

Ø  Rivets:

These are also not threaded but have a head on one side. These are used to do permanent fastening. Once these are installed, they cannot be removed without damaging the object or rivet itself.
