Abstract
A fastener with a special head having a threaded recess and torque receiving recesses is matched to a tool which threadably engages the head and utilizes the threaded engagement to provide a solid base for torque applicators, such as drive pins, drive blades or a serrated drive disc so that high torque fasteners which otherwise would use Phillips, Tri-wing or Reed and Prince torquing systems, can be installed and removed without fear of the torquing tool camming out of their heads and thereby ruining them or requiring extensive jigs or other holding devices to prevent such camming action.
