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 hardened steel 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.

This set of flat washers are made of high quality copper of good electrical conductivity and thermal conductivity.
Flat washers can spread a load, and prevent damage to the surface being fixed, and insulate steel screws from surface.
