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 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. Each ARP accessory stud or bolt kit includes the specific numberof parts for your application, plus premium-quality washers and hex or 12-point nuts, as required. Studs are manufactured with a unique nut-starter nose that helps prevent cross threading Studs and bolts come either black oxide chrome moly or 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.
