Plain Washer Manufacturers in India: About Plain Washer Fasteners -
A Plain Washer is a thin plate (usually disk-shaped) with a hole (usually in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring washer, wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers often have an outer diameter (OD) about twice their inner diameter (ID), but this can vary quite widely. Washers are usually made of metal or plastic depending on the use.
