The jaws are pivotable relative to each other. The jaws are attached to a draw stud. The draw stud is formed from an elongated cylinder which has a conventional thread form formed on one end thereof and a plurality of alternating annular grooves and lands formed on the other end thereof. The alternating annular grooves and lands formed on the jaws mesh with the alternating annular grooves and lands formed on the draw stud to mate the jaws with the draw stud.
