A fastener is a non-permanent or permanent mechanical tool that rigidly connects or affixes two surfaces or objects together. Non-permanent fasteners can easily be removed without damaging the joined materials. The removal of permanent fasteners might require substantial force and might damage the connected surfaces. Permanent Standard Fasteners are designed to be a long lasting form of secure connection.

The wide range of fasteners includes screws, nails, nuts, bolts, and washers that come in different sizes, types, and configurations. Fasteners are one of the most used tools for building, fabricating, and configuring a variety of products and industrial equipment.

Non-Permanent Threaded Fasteners

The variability between fasteners is due to the extreme forces that are placed on them. The purpose of fasteners is to hold parts, components, and pieces of machinery together in the presence of excessive vibrations and pressure while retaining the ability to disassemble the pieces when necessary.

Washers are small, circular, metal disc in the shape of an annulus, halo, donut, or ring that is used to distribute the force of a screw, bolt, or nut. They can relieve friction, stop leakages, maintain tension, prevent corrosion, and serve as a spacer or separator. The wide and varied uses of washers has made them a necessity in a number of applications.

The types of washers can be divided into three categories, which are plain, spring, and lock. In each of the categories are specialized forms that are designed to serve a specific or unusual function.

The many functions of washers include:

1. Reduction of friction

2. Distribution of pressure

3. Blockage, cessation, or elimination of leakage

4. Separation of components

5. Enhancement and securing of connections from vibrations and shock
