摘要
An improved fastener system includes a threaded pin (12) and a bit (16). The pin contains a recess (39) in a threaded end of the pin for receiving the bit (16), thus holding the pin (12) against rotation during application of a nut (14) on the pin (12). In one embodiment, the recess (39) includes a pair of substantially perpendicular intersecting slots (40) extending completely across an end face of the threaded end of the pin (12), with an aperture located at the intersection of the slots (40). A plurality of splines (26) are located on an end of the bit (16) for engaging the slots of the recess. The splines (26) are oriented on the bit (16) to mirror the configuration of the recess (39). Additionally, a pilot (28) extends from the splines (26) on the end of the bit (16) for engaging the aperture of the recess (39) and centering the bit (16) during use.
