When I left the Class 3 world I left it behind.  

Seriously, I have no idea.  I just remember that matrix with the nominal
torque values and tolerance for all the applications we used.  At the time 
I assumed it was an industry standard (I wasn't involved in the details of 
the specifications at the time, just verifying compliance) but as I look 
back it may have been an in-house doc, a fastener manufacturer's recommendations, 
or, as brought up in another reply, a machinist's handbook.  I'm thinking
it was a combination of the first and second, though.  

I have no direct responsibility for fasterner issues here, and the responses 
to the few queries I made today suggest I should only go deeper when I am in 
need of a new project.

I like that answer and it would be mine as well. One question though, posed
by my client Ken Carlile at ECC, is where do we find the torque values used
on PCB assemtlies? I have lost track of this information since the demise of
275, etc., days.
