Don't relate to them, just tell them that you are buying chrome bolts for your water pump and let him wonder. I have numerous supply houses around me that carry grade 5 and grade eight bolts---will never buy a bolt of a lower grade than a 5, ever again. If I am going to install something, then it is going on without any chance of me breaking it or it breaking from vibration. I have only one that has the chrome plated bolt supply, they get a lot of Harley owners in there. I even have a "Fastenal" company store here that has stainless steel bolts, they are just about the same tensile strength as a grade 5, but not quite. If you want a quality stainless steel bolt, then you have to purchase bolts through ARP and they are expensive.
