Flat Washer

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).

Flat washers are used to increase the bearing surface of a nut or fastener's head thus spreading the clamping force over a larger area.

They can be useful when working with soft materials and oversized or irregular shaped holes.

Flat washers are also known as plain washers.
