Your cart is empty.ARP's premium grade header bolt kit is an excellent choice to facilitate the installation of your vehicle's exhaust headers. 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 1.000 under head length, and the 12 piece set includes premium-quality washers.

The heads on these are very small, they do not match the ARP bolts that I already have, but the ad does not specify head size so I assumed ARP made them all the same, also there's not enough in the pack to bolt up two headers which seems pointless. I was in a jam so I had to use them, now I have two different sized bolt heads in my headers which not only looks dumb but it's hard to properly tighten these because the wrench size is so small

They are the best. Just ensure you order the correct finish for your project. Sometimes it defalts to a different finish.

They are ARP, what else to say. 12 point heads, easy to install and tighten on headers with close clearances.
