I have heard the same thing about grade 5/8 for many years but have yet to read anything proven this true which is a totally other subject. Bolts are rated by the yield strength and tensile strength. Shear falls into the tensile category. Can someone support their statements about 1) stainless being unable to carry equivalent grade 5 loads and 2) just for giggles that grade 5 are better for shear forces and 8 for clamping? Like I said above, in the earlier days of stainless fastener use they were equivalent to about a grade 2 and I agree were for show only. I specifically spoke to Doc at Doc's Hotrods about this grade 5/8 issue. I bought stainless trailing arm bolts among other things. Look at my sig, this will not be a show car...I mean truck.

Edit for: we can go to email/PM to discuss this.
