This is the most important part of any good cnc machinist calculator appyou wont get far without speeds and feeds! = Nominal allowance. , MINOR The only difference between the internal UNJ thread and the standard UN threaded is that the UNJ thread has a larger minor diameter.

PD (basic) is the same for UN, UNR, UNJ, external, internal. 2.) UNJ carries this even further, so far that the minor diameter of the bolt is increased. .2211, .
