Washers are usually metal or plastic.High quality capscrews require hardened steel washers to prevent the loss of pre-load to Brinelling after the torque is applied.Rubber or fiber gaskets used in taps to stop the flow of water are sometimes referred to colloquially as washers;while they may look similar,however,washers and gaskets are usually designed for different functions and made differently.Washers are also important for preventing galvanic corrosion,particularly by insulating steel screws from aluminum surfaces.
