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.
