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.
ARP Header Bolts & Header Studs made from Stainless 300 material are not affected by corrosion or extreme heat, making them ideal for the application.
Additionally, the compact 12-point nut allows for easy socket access 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.
ARP Header Bolts & Header Studs are available 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.
Studs are measured OAL (Overall Length) and Bolts are measured UHL (Under Head Length).
