The ARP Stainless material is 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. Studs are manufactured with a unique nut-starter nose that helps prevent cross-threading. Studs and bolts come either black oxide chrome moly or polished ARP Stainless. Both are nominally rated at 180,000 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 prevent loosening. HEADER BOLTS & STUDS Special “NASCAR” model header bolts are available that are drilled for use of safe- ty wire. Perfect for any racer who desires the ultimate in security. Available for small block and big block Chevrolet engines, plus many “universal” applications. Drilled for safety wire
