I think maybe you would like to look at ANSI/ASME B1.12, Class 5, interference fit thread, for more detail. There are so many tolerance defined, example pitch diameter tolerance, major and minor diameter tolerances and etc. Also, the TPI also plays an very important role here.

Gentlemen,

Thank you for the replies.

Umang, thanks for the welcome. Unfortunately, none of the websites gave me the requested tolerances.

Jerry, it seems like ANSI/ASME B1.12, Class 5,is not available anymore. I am trying to get the Fed-Std-H28/23.

I do not know if I downloaded the entire file, but the tolerances for the setting plugs for class 5 threads are not listed on this spec.
I will try to get the ANSI/ASME B1.12...

For sure you have downloaded the entire file. Problem is the tolerance that you wanted is not listed in Fed-Std-H28/23

See attachment, probably you will find this useful. It's from ANSI/ASME B1.12
