ITEM NAME:   WASHER,LOCK
DEFINITION:  A washer which is usually round with a centrally located hole. Its
             edges and two bearing surfaces are so designed that applied pressure
             brings into play the spring tension and/or frictional locking
             principle which materially resists any tendency toward turning. It may
             be made of one or two pieces
