Abstract
An integral stud member having shank portions extending from either side of a radially extending flange. A first shank portion including thread convolutions with means to form mating internal threads in an associated workpiece. The surface of the flange opposing the first shank including generally radially extending rib-like surfaces which serve as the means to drive the fastener in place. The rib structures are configured to permit a driver to softly engage the flange and to lock the fastener from backing out of the workpiece after a secondary work surface has been clamped over the flange.
