7.8E HEAVY DUTY SPLIT-RING RETAINING NUT
The heavy duty split-ring retaining nut is used in oversize punching applications that require a punch
with a 2 inch (50mm) shank diameter (E). Follow the instructions in SECTION 6.1 for proper punch
and die alignment. This retaining nut requires a pin wrench (F) which should be ordered when
ordering the nut. To use the heavy duty split-ring retaining nut, remove the six socket head cap screws
(D). Slide the retaining ring (C) over the punch shank. Place the split-rings (B) into the groove in the
punch. Place the ring nut (A) on the punch and replace the six socket head cap screws (D).
