ABSTRACT:
The disclosed method features an automatic high production process of forming a socket wrench and other elongated hollow parts such as a nutdriver from a tubular metal workpiece. The method of making a nutdriver includes extruding a workpiece through a tapered female die to reduce both the inside and outside diameters at one end of the workpiece and along a predetermined portion of its length from that one end of the workpiece. A recess of non-circular cross section is formed at the other end of the workpiece. In the method of making a socket wrench, an additional step is included in forming another recess of non-circular cross section at the reduced end of the workpiece.
