Now you can use premium-quality ARP chromoly bolts to install most anything on a car, boat, or trailer. These specially heat-treated 8740 chromoly fasteners feature a black oxide finish. They are nominally rated at 180,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware.
