A washer is a thin plate with a hole (typically in the middle) that is normally used to distribute the load of a thread fastener, such as a bolt or nut. Washers often have an outer diameter about twice their inner diameter, but this can vary quite widely.
Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Coatings can be used in attempt to reduce wear and friction either by hardening their surface, or providing a solid lubricant (i.e. a self-lubricating surface).
