Abstract

A fastener (10) has a body (20) and a cage (30) with cam surfaces (42, 44') formed on interengaging components (28, 33) to inhibit relative rotation. In one embodiment a washer (36) is interposed between said surfaces and has oppositely directed faces (38, 40) with cam surfaces formed on them. In a further embodiment, the underside of the cage has serrations formed on it.
