I THINK I know what I need..... Does anyone have a link to bolt clamping load tables? Correct me if I am wrong, but I think this equates to "bolt failure load", assuming the bolt is in steel, properly lubed, torqued, etc. I am just curious about what load a 1/2"-NF, SAE grade 8 bolt will take compared to a 9/16", same quality. I built a pintel hook attachment plate and am wondering what size bolts to use in it. Thanks. PS: I have googled, etc, and the engineering pages I get a link to give me a headache. j
