The ARP bolts are very well engineered. And are much better quality than just about any other stainless fasteners on the market. True Stainless does not have the flex of a grade 8 bolt(of same size), but the sizes that are used compencate for that. Berkely installs Stainless bolts in all there pump parts from the factory, even on the race pumps. The only thing is, NJBA rules state that the loader be through bolted and with black oxide grade 8 hardware, and it is a real good idea !!!
