To maintain a reputation for "zero defects", ensure optimum quality control, and produce fasteners of exceptionally high quality, ARP controls all aspects of the manufacturing process, performing all operations in-house where they can be closely monitored. ARP takes extraordinary steps to produce the very finest products of their kind on the market today. Manufactured from ARP's proprietary steel alloy "Stainless 300" and polished to produce a beautiful finish, these components are tolerant of heat, virtually impervious to rust and corrosion, and they are rated at 170,000 psi tensile strength, which is substantially stronger than Grade 8 hardware. The 3/8" diameter bolts are a compact 12-point style that are great for tight, hard-to-reach areas, have a .750 under head length, and the 12 piece set includes premium-quality washers.

They fit fine, and it’s ARP so the quality is good. Though even in a tight area these are very short. They hold but they are not as long as really desirable especially when you strip out the first couple of threads on an aluminum head. The 12 point head is much more of a head ache then it’s worth though…

Small head and short stainless bolts are great for headers that are tight !
