Washer sizes correspond to the screw/bolt diameter they fit. For example, a 1/2” washer fits a 1/2” bolt, and therefore has an inner diameter of just over 1/2”.

Threaded fasteners do a more reliable job when accompanied by washers. Most notably, washers protect the surface from damage during installation. They distribute the pressure and prevent the fastener from moving or corroding. Skipping on washers can dramatically reduce the lifespan of how your product is put together.
Does the washer go on the bolt or nut side?

Unlike flat washers, which are placed on both the bolt and nut side, spring washers only go on the nut side of the fastener to establish a bond. A spring washer offers axial flexibility that’s intended to prevent loosening of the fastener with which it’s paired.
What is the difference between a flat washer and a spring washer?
Plain washers are flat, whereas spring washers are curved. For most applications, plain washers are typically used. For machines and objects that vibrate, spring washers are recommended. Spring washers are unique because they provide an axial load that counters vibrations and, thus, prevents fasteners from loosening.

How to Calculate the Cubic Feet of a Washer

What is difference bolt and screw?
A bolt is a non-tapered fastener that uses a washer and nut to hold objects together. A screw is a tapered fastener that mates with an existing thread or creates its own thread in a material as it turns.
What are flat washers?
Flat washers are used to increase the bearing surface of a nut or fastener’s head thus spreading the clamping force over a larger area. They can be useful when working with soft materials and oversized or irregular shaped holes. Washer size refers to its nominal hole size and is based on screw size.

When used correctly, a lock washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the lock washer on first, below the fastener. If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.
