Washer (hardware)

（重定向自Split washer）

Assorted washers: flat, split, star and insulated

A plain washer and a spring washer are placed on a bolt between the nut (on the threaded end) and the bolt head.

A washer is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut. Other uses are as a spacer, spring (belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers usually have an outer diameter (OD) about twice the width of their inner diameter (ID).
