Metal Washers

Some of the most widely used fastener hardware there is, flat washers are thin, disc-shaped pieces of material that are installed between a fastener and the mating material. Metal flat washers are commonly used for load distribution, as spacers, as preload indicators, and in applications in which the diameter of the hole is larger than diameter of the head of the fastener that is being installed.

Specialized flat washers and those made from other materials are often used as springs, wear pads, and vibration reducers, among dozens of other potential applications.
