A thin flat metal or plastic item of various peripheral shapes having a solid or laminated cross-section. It is designed to maintain a predetermined distance between two surfaces.

When thickness and/or outside diameter or shortest distance across peripheral flats is designated as a tolerance dimension, the maximum dimension will be used to determine compliance.
