S/S Bolt Kit - 6pt. (5) 3/8-16 x .750

The S/S Bolt Kit - 6pt. (5) 3/8-16 x .750 from ARP is a critical fastening solution designed for precision assembly in tactical, automotive, and industrial applications where reliability under stress is non-negotiable. This five-bolt stainless steel kit delivers the corrosion resistance and structural integrity demanded by law enforcement armaments, military weapons platforms, and high-performance mechanical systems.

Each bolt is engineered to withstand vibration, thermal cycling, and the extreme pressures common in duty-grade equipment where fastener failure is not an option. Constructed from premium stainless steel, the S/S Bolt Kit features a robust 3/8-16 UNC thread pitch—a standard in tactical firearm assemblies and precision machinery—with a .750-inch length optimized for shallow-depth applications without compromising clamping force.

The 6-point socket head design provides superior contact geometry compared to 4-point heads, distributing load across more contact surfaces and reducing the risk of rounding or stripping during installation or removal in field conditions. This bolt kit is ideal for gunsmiths, armourers, and tactical equipment technicians assembling or servicing rifle components, optic mounts, rail systems, and protective gear where exposure to moisture and salt is a concern.
