About Flat Washers

The most common washer style, flat washers install between the fastened material's surface and a nut or bolt head to help distribute the load or reduce friction.

These washers are either thicker than standard for leveling or spacing, or they have a larger outer diameter to cover enlarged holes. Those with an oversized OD are also known as fender washers.
