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-piece stainless steel bolt 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 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. The specification ensures compatibility with standard SAE metric tooling and delivers consistent torque characteristics critical for reproducible assembly across multiple units or maintenance cycles.

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, salt spray, or harsh environmental conditions demands corrosion-resistant fasteners. The five-piece quantity supports small-scale repairs, custom builds, or replacement of worn fasteners in modular weapon systems and accessories. Stainless steel construction eliminates the need for secondary coatings or maintenance treatments, ensuring long service life in field-deployed equipment while maintaining a professional, corrosion-free appearance.
