Universal stud kit broached with locking nuts, 12-point, 3/8", 14 pack, 1.125" overall length, black oxide, ARP header studs 100-1415.
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 and header studs made from stainless 300 material are not affected by corrosion or extreme heat, making them ideal for the application.
The compact 12-point nut allows easy access for a socket close to the pipe.
Each ARP accessory stud or bolt kit includes the specific number of parts for your application, along with 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 and header studs 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.
Studs are measured OAL (overall length) and bolts are measured UHL (under head length).
