  • the axial protrusions 80 of the socket 34 allow the socket 34 to be manufactured using a cold heading process which greatly reduces manufacturing costs. While cold heading can be used to manufacture the body of a conventional socket with annular protrusions on the inner diameter, the annular protrusions need to be machined using a secondary process (e.g., turning). This secondary process negates any cost efficiencies associated with the cold heading process.
  • the axial protrusions 80 allow the socket 34 to be cold headed to net shape without the need for additional processes to form the axial protrusions 80.
