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.
What?s more, the compact 12-point nut lets you easily slip a socket close to the pipe. Studs are manufactured 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 are nominally rated at 180,000 psi tensile strength; substantially stronger than Grade 8 hardware. Specially drilled "NASCAR" models are available for those who wish to safety wire their header bolts to prevent loosening.
