Abstract
A hybrid washer has an essentially disk-shaped body having an outer ring, an inner ring, and a bore extending through the inner ring. The outer ring has an engagement surface having a plurality of wedges with each wedge having a raised edge that extends radially and perpendicularly from a longitudinal axis projecting through the bore. The inner ring has a pair of spaced-apart essentially flat surfaces in overlying relation with one another. The wedges form a plurality of crests contoured to frictionally engage a mating surface from a locking washer to fix the locking washer against the hybrid washer.
