Thread Depth
12-JAN-2008

Thread Depth

To accurately measure the nominal wall thickness of this 1" thru-hull I first needed to measure the thread depth that had been cut into it. I used the depth gauge of my calipers to figure out the depth of the thread cut. In this photo you'll notice a little tab of metal sticking out the right side of the caliper. That tab of metal was the actual thread depth from the pointed outer surface of the threads to the bottom of the thread valleys.
