Now you can use premium quality ARP stainless steel or chrome moly fasteners to install most anything on a car, boat or trailer. The specially alloyed ARP 300 stainless steel and heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 180,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware.

Whats more, you cant beat the gorgeous looks of ARPs specially polished stainless steel fasteners, and their ability to resist rust. Theyre truly maintenance free!

You can get 5-packs (washers included) of any diameter bolt from 1/4 to 1/2 or M6 to M12 in lengths ranging from 1/2 to 6, with ARP12-point heads. Matching nuts are also available
