ARP® 8740 Chrome Moly Header Bolt Kit (100-1102) Black is the color. Header Coating: Painted. ARP manufactures a variety of premium grade bolt and stud kits to aid in the installation of exhaust headers, including the popular stainless stud kit with 12-point nuts. The stainless material is resistant to corrosion and extreme heat, making it ideal for the application.
Furthermore, the compact 12-point nut allows you to easily slip a socket close to the pipe. Each ARP accessory stud or bolt kit includes the exact number of parts needed for your application, as well as premium-quality washers and hex or 12-point nuts as needed. Studs have a unique nut-starter nose that helps prevent crossthreading. Studs and bolts are available in either Black Oxide chrome moly or Stainless steel. Both are nominally rated at 180,000 psi tensile strength, making them significantly stronger than Grade 8 hardware. Specially drilled "NASCAR" models are available for those who want to safety wire their header bolts to prevent them from loosening.
