ABSTRACT:
A die spring retainer for vertically affixing a die spring to a die set is configured as a generally circular blank defining a central opening adapted to receive a pilot screw therein. The blank includes a major portion having a first diameter and a minor portion having a second diameter less than the first diameter. The minor portion constitutes approximately 30 degrees to 120 degrees of the external circumference of the blank. The blank is fabricated from a deformable material and deforms under compression to the configuration of the first coil of the spring, thus securely affixing the die spring to a die set.
