         Cutting threads is not the same as rolling threads. On
high-strength bolts, they roll the threads on because it is much stronger
than cutting the threads.

         Probably the right way to do this is to get the right length
high-strength bolts or to get studs the correct length.

 
Hi Bill,
 
All true of course, but not easily available as far as I can tell.  Fortunately, I came across a set of custom made bolts before I had to do any significant research on finding an off the shelf bolt for this.  One of my projects will be measure the bolts, and threads, so I can see what might be available.  I do believe a rethreaded 12A bolt would be fine though. 
 
Cheers,
Rusty
