WebDear Threader, I was told in school, that you need at least the diameter of tap, in length of thread engagement. Example: If you were taping a 3/8-16 thread hole. You would need at least 3/8 of an inch in threads minumin. 3/8”= .375 .375 * 16 = 6 Minumin of 6 thread. Engagement: one revolution = one thread engagement. Web23 nov. 2015 · I have always used the rule of thumb that the bolt has to be engaged at least one bolt diameter. This partly comes from looking at structural nuts. Structural nuts develop the full strength of the bolt in tension. These nuts typically engage about one bolt diameter. Share Improve this answer Follow answered Nov 21, 2015 at 19:42 hazzey ♦
