Industry-leading fastener manufacturer ARP makes it easy to upgrade factory hardware with premium quality polished stainless steel bolts that come in handy 5-packs by size. In addition to large bolts that range from 1/2” to 1/4” in diameter, ARP offers #10-32, #10-24 and the new #8-32 sizes.
Manufactured in-house at ARP’s California facilities, the new #8-32 bolts feature 12-point heads and are available in .375”, .500*, .625”, .750”, .875”, 1.000”. 1.125”, 1.250”, 1.375” and 1.500” underhead lengths and can be employed for a variety of tasks in a vehicle’s engine compartment, interior and elsewhere.
All of ARP accessory fasteners (polished stainless steel or black oxide finished 8740 chrome moly) are nominally rated at 180,000 psi tensile strength —fully 20% stronger than Grade 8 hardware. As an additional benefit, the stainless steel bolts are virtually impervious to the elements.
