internal threads
(OP)
1)i am seeking technical information concerning 2-56 unc 3B internal threads. specifically the differences between the strength, using a cut tap and using a roll tap.
2)also the dimensional differences between the minor diameters using a cut tap and a roll tap
3)is there a mil-spec that authorizes the use of a roll tap in place of a cut tap

This forum can be a little quiet so you may not get the answer you need. forum725: Welding, Bonding & Fastener engineering may be a better place, try not to double post though perhaps redflag this post (link below) and ask for it to be moved or something.
KENAT, probably the least qualified checker you'll ever meet...

As far as strength determination, a machine design textbook that you would be assigned during your junior or senior year in college, will show you how to calculate that.
