Washers are thin disk-shaped plates with a hole that is used to distribute the load of a threaded fastener such as a bolt or nut; often have an outer diameter (OD) about twice their inner diameter (ID), but this can vary based upon the washer. Washers come in many different varieties; flat washers, split lock washers, toothed lock washers, beveled washers in both steel and iron, etc.
