Lol, I try to contain myself from replying to every post Tom. I'd think the forum gets rather tired of my many posts. I'm kinda' like the nerdy kid in grade school that raises their hand to answer every question... oh oh oh I know the answer!FOG, I am surprised Rick did not chime in on bolt head stamps. They indicate the Grade/ Tensile strength of a given hex head bolt. If you use Grade 5 or 8 you are in good shape.
