Percent of thread (obsolete term) Per ASME B1.7-2006 Definitions [ back to main page ]
Percent of thread (obsolete term): the ratio in percent of the actual height of thread to the value 0.75 H. This is a theoretical value based upon the old American National Thread Profile. A 100% value cannot actually be achieved since the basic height of thread for UN and M profiles is 0.625 H, and for UNJ and MJ is 0.5625 H.
