ARP Header Bolts & Header Studs For Oldsmobile. 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.

ARP Header Bolts & Header Studs that are Stainless 300 material are 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 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 come either black oxide chrome moly or Stainless 300. Both are nominally rated at 170,000 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 Special “NASCAR” model prevent loosening.
