Hoyt, Thanks for the clarification, as I said it's been a few years, and I may of only remembered the part that was relevant at the time. That's interesting, I don't want to get any deeper. I can see that stud has a different function than say a bolt. I'll try and remember that rule too. I'm curious have you reached the maximum strenght at the "square" or 1.5 times or will additional threads add some additional strenght?
