(R) HEAD RADIUS
NOTE: The HI-LOK pin has a slight radius under its head.
After drilling, deburr the edge of the hole. This
permits the head to fully seat in the hole. See the
list in this figure for head radius dimensions. For
example, the 3/16 protruding head (HL 18-6 series)
(R)
has a .015/.025 radius while the 3/16 flush head
(HL 19-6 series) has a .025/.030 radius.
