Washers
C Washers
A C washer is a flat washer with a slot cut to the bore so it slides sideways onto a bolt, stud or shaft without removing the fastener. It is used mainly as a shim or spacer in an existing assembly.
Used to pack, shim or align parts on shafts and bolted joints that cannot be disassembled. Bought by maintenance teams, machine builders and jig makers.
