Description:

The

washer is a thin disk-shaped plate with a hole 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, wear pad, pre-load indicating

device, locking device, and to reduce vibration. High-quality bolted

joints require washers to prevent the loss of pre-load

after the torque is applied. Washers are also important for preventing

galvanic corrosion, particularly by insulating steel screws from

aluminum surfaces.
