Product Overview

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. What’s more, you can’t beat the gorgeous looks of ARP’s specially polished stainless steel fasteners, and their ability to resist rust. They’re 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
