A washer is a thin round plate with a hole that is in the centre. They are used for two main reasons: To minimise scouring or scratch damage to mating material as a result of nut rotation and to
increase the effective bearing surface of the bolt and or nut. That is, to distribute the load of a threaded fastener over a larger area and prevent deformation of the bearing surfaces.
