ARP 646-4000 Fasteners - Hex Bolts
1/2-13 x 4
Standard Hex Bolt
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
