There is only a slight angle of the threads difference between
Unified and SAE threads. If you use a Unified bolt as the tap and then
thread an SAE bolt in your ok; there is only a slight bit of interference
and the torque will fall within the range. If you thread a Unified bolt
into an SAE nut; it will feel loose and you can torque the bolt but it is
not the best scenario for a critical part attachment. The best way is to
use Unified with Unified and SAE with SAE.
I have 2 old catalog; Metric and Multistandard Components Corp and
Manhattan Supply Company which both list British and Unified standards. I
think they are still around and they both carried bolts and tap and die
parts. I'm sure there are others.

Thanks for a clear explanantion of what was happening. I suspected some kind
of difference since I could almost run the original bolts through die by
hand alone, then the resistance I felt with the new bolts made me wonder if
I was getting into a problem. If so better to eliminate it now. I will have
to see about the availability of the UNF bolts here. I have just
changed the bolts the threaded part is still original UNF
