UNJ thread specs.

[hdrider63]

Hi,
I need help finding thread specs for UNJ threads. Can anyone give me a link to get tolerances for a 1 5/16-12 UNJ 3B thread??
Thanks,
Jeff

Here is a neat piece of software, ME Threads that you should get. It is very inexpensive

You can also use software "QMSys Threags and Gauges".
Each QMSYS software is available as a free trial for 14 days or 30 uses.
