ARP M8 X 1.25 X 38mm broached stud kit - 4pcs 400-8002

ARP has developed some innovative multi-purpose accessory studs that can be used for exhaust systems, intake manifold and a host of other uses. The studs are manufactured from a specially alloyed Stainless material developed by ARP and are impervious to the rust and corrosion that plagues ordinary fasteners. This stainless steel alloy is nominally rated at 180,000 psi tensile strength, which is substantially stronger than Grade 8 hardware. Ideally suited for installing exhaust headers, most have a unique “nut starter” nose and a hex-broached tip – which allows the studs to easily be installed using an Allen wrench. The studs come with “easy wrenching” 12-point nuts and flat washers.
