Washers are a thin plate with a hole in the middle (typically looks like a disk). You may see it a small part but it is beneficial when distributing the load of the fasteners like nut or bolt.

Here are the other things that you need to know about washers:

What are the types of washers?

Washers can be categorized into three types – plain washers, spring washers and locking washers. The plain washers spread load at the same time averts damage to the surface. Examples include flat washer, fender washer, spherical washer, anchor washer and torque washer.

What are the standards of washers?

If you refer to the British Standard created in 1968, they identify washers in different forms. Form A refers to washers with normal diameter with normal thickness. Form B, on the other hand, refers to washers with normal diameter but light thickness. Form C refers to washers with large diameter with normal thickness. Form D refers to washers with a large diameter but light thickness. Form E is a washer with a larger diameter but normal thickness. Form F refers to washers with a larger diameter but normal thickness and Form G is a washer with the largest diameter and larger thickness.

What are the materials used to fabricate washers?

Washers can be made from different materials like steel (like carbon steel, stainless steel, and spring steel), metal (like brass, copper, aluminum, bronze, iron, titanium and zinc), alloy (like silicon bronze, monel and Hastelloy), plastic (like Teflon and polyethylene), Nylon, and specialty washers (like fibers, leather, felt and rubber).

What are the techniques used for corrosion resistance?

Corrosion resistance describes how well a metal withstands damage caused by oxidation. Techniques include metallic coatings, electroplating, phosphating, bluing (or browning) and chemical plating.

Where to buy washers?

Washers are little things that make a huge impact at the end of the day. It should be considered whatever mechanical projects you have. The good thing is you can find washers immediately.
