Tab Washers

Tab washers, also known as tab lock washers, are used to keep threaded fasteners from rotating. Whereas most lock washers rely on friction or a spring load between the fastener and the mating surface to prevent loosening, tab washers bend against the fastener’s side to sustain a fixed position.
