An improved fastener system includes a threaded pin and a bit. The pin contains a recess in a threaded end of the pin for receiving the bit, thus holding the pin against rotation during application of a nut on the pin. In one embodiment, the recess includes a pair of substantially perpendicular intersecting slots extending completely across an end face of the threaded end of the pin, with an aperture located at the intersection of the slots. A plurality of splines are located on an end of the bit for engaging the slots of the recess. The splines are oriented on the bit to mirror the configuration of the recess. Additionally, a pilot extends from the splines on the end of the bit for engaging the aperture of the recess and centering the bit during use.
