ARP has developed some innovative multi-purpose accessory studs that feature a “nut starter” nose and a hex-broached tip for ease of installation that can be used for exhaust systems, intake manifold and a host of other uses. The studs are manufactured from a specially alloyed ARP Stainless developed by ARP that is rated at 180,000 tensile strength and are resistant to the rust and corrosion that plagues ordinary fasteners. The studs come with 12-point nuts and flat washers.
