Details

*controlled for repeatability and ease of adjustment when using FZP20 cages. The measurement is from the thread end of the tool to outer corner
of the countersink diameter and is combined with a controlled thread length and body length so that minimal adjustment of the microstop should be
necessary.

**shown as .410" in early Briles documents. We provide this detail with 1/2" body diameter
