ARP header bolts and studs are available in black oxide-coated chromoly steel. The studs are rated up to 170,000 psi making them ideal for all applications. All the studs come with a special nut starter nose to prevent cross threading. The nuts for the head studs feature 6-point or 12-point, so they can be tightened easily in small increments.
