Thanks so much. I searched the internet for at least 2 hrs without any success. I knew the only difference between the UNF and the UNJF is the tighter root diameter and I needed to know the radius tolerance on the root.

Very cool software. Thanks for the link.

I know you're doing an external thread this time, but just in case you ever do a J-series internal thread, notice that the minor diameter is larger than the one on the UNF.

I meant that I posted the question becuase I was only missing that spec.

Thanks mrainey
I guess it would have to be opposite for the internal. Hopefully I will not have to make any internal threads.
