Abstract: A one piece pin, adapted to be driven by a motor, includes a threaded rod having a self drilling end at one end of the threads of the rod. The self drilling end includes a transversely positioned flat portion integral with the rod having a drilling edge with a point. A flat head is formed on the rod at the opposite end of the threads, the head having a pair of diametrically opposite notches which permit the head to be grasped by a tool. A divisible shank is attached to the heads by a zone of reduced resistance to rupture torque.
