Description

The ARP 480-1201 is a set of 14 stainless steel header bolts designed for Oldsmobile V8 engines. These bolts feature a 12-point head style and a 3/8 in.-16 thread size with a 0.750 in. underhead length. The polished stainless steel construction offers high corrosion and heat resistance, with a tensile strength of 170,000 psi. ARP stainless steel header bolts are 15 percent stronger than Grade 8 steel and have a compact head to fit into tight spaces next to headers. Anti-seize should be used on all stainless steel fasteners.
