Superstrut® E148-1/2EGC Lock Washer, 1/2 in, 1/2 in ID, Steel

Superstrut® self-aligning channel nuts are designed to provide resistance to pullout and resistance to side slip in excess of the full strength of the channels with which they are used. The extreme resistance to side slip result from the unique design of the alternate teeth, spaced and designed to develop a wedging action that increases with pressure or load.
