Pack Washer

A washer is a thick 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 bolt or nut. Pack Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminum surfaces.
