Abstract
A threaded fastener having a threaded shaft with a head disposed on a portion thereof and a deflectable flange protruding outwardly from the shaft at or near the head. The deflectable flange has a generally concave surface facing toward a leading end of the fastener shaft. A protuberance is disposed on the shaft and spaced apart axially from the generally concave surface of the deflectable flange to limit compression of a fixture clamped between the fastener head and a work surface.
