7.11E HEAVY DUTY SPLIT RING RETAINING NUT
SEE FIGURE 26 BELOW.
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). This retaining nut requires a pin wrench (F), which should be
ordered when ordering the nut. Follow the instructions in SECTION 6.1 for proper punch and die
alignment.
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-ring (B) into the groove on the punch. Place the
ring nut (A) on the punch and replace the six socket head cap screws (D).
