ARP manufactures a variety of premium grade bolt and stud kits to facilitate installation of exhaust headers including the popular stainless stud kit with 12-point nuts. The ARP Stainless material is not affected by corrosion or extreme heat, making it ideal for the application. Whats more, the compact 12-point nut lets you easily slip a socket close to the pipe.

ARP manufactures their studs with a unique nut-starter nose that helps prevent cross-threading. Studs and bolts come either black oxide chrome moly or polished ARP Stainless, both nominally rated at 180,000 psi tensile strength, substantially stronger than Grade 8 hardware.
