A square washer is a thin plate with a hole that is normally in the centre. They are used to minimise scouring or scratch damage to mating material as a result of nut rotation.
These washers are also great 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.
