ARP manufactures a variety of premium-grade bolt and stud kits to facilitate the installation of exhaust headers, including the popular stainless stud kit with 12-point nuts.
The Stainless 300 material is not affected by extreme heat or corrosion, making it ideal for the application.
Moreover, 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 specific number of 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 in either black oxide chrome moly or Stainless 300.
Both are nominally rated at 170,000 psi tensile strength, which is 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.
