A method comprises steps of providing bar stock, cutting the stock to form a rod-shaped blank, and stamp-forming a ball section on a first end of the blank in a transfer die. The method further includes stamp-forming an apertured flattened section on a second end of the blank to form a final product in the transfer die, and axially striking opposing ends to accurately form a length of the blank. A related transfer die apparatus includes stations for cutting and then stamp-forming a ball section on a first end of the blank, and stamp-forming an apertured flattened section on a second end of the blank to form a final product. |
