Abstract
A fastener member in the nature of a nut or bolt which bears against an external member which is softer than the fastener member including a body portion having first and second ends, a spin washer mounted on the first end of the body portion, internal and external surfaces on the spin washer, a first surface on the external surface for bearing the external member with a first frictional force, and a second surface on the internal surface of the spin washer for bearing against the first end of the fastener member with a second frictional force which is less than the first frictional force to thereby permit relative rotation between the first end of the fastener member and the internal surface of the spin washer while the spin washer remains in nonrotatable engagement with the external member.
