A washer is a thin disk of lead or oiled leather with a hole, usually in the center, used to lay nuts and heads of screws. They are normally used to support a load torque. Among other uses may be the spacer, spring, preload indicator device and as a safety device. Washers are primarily made of metal or plastic. The screws with heads high quality require some hard metal washers to prevent loss of preload once the torque is applied. Rubber or fiber seals used in covers and gaskets to prevent leakage of liquids (water, oil, etc.) are sometimes the same as a washer, but its function is different. Washers are also important for preventing galvanic corrosion, specifically by insulating metal screws from aluminum surfaces.
