DIN9021 Stainless Steel Big Washer (thick 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). Washers usually have an outer diameter (OD) about twice
the width of their inner diameter (ID).Washers are usually metal or
plastic. High quality bolted joints require hardened steel washers
to prevent the loss of pre-load due to Brinelling after the torque
is
applied.
