SS Bolt Kit - 12pt 5pk 3/8 x 2.500

The SS Bolt Kit - 12pt 5pk 3/8 x 2.500 by ARP is a critical fastening solution for firearms, automotive, and precision machinery applications where reliability under extreme stress is non-negotiable. These stainless steel bolts are engineered for professionals who demand corrosion resistance, tensile strength, and repeatability in high-performance environments. Whether you're building a custom rifle platform, assembling tactical equipment, or maintaining critical mechanical systems, this five-pack kit provides the dependable hardware necessary for secure assembly and lasting durability.

Constructed from 300M stainless steel, the SS Bolt Kit features a 12-point head design that provides superior grip and reduced fastener slip compared to conventional six-point fasteners. The 3/8-inch diameter shaft and 2.500-inch length are precision-manufactured to exact tolerances, ensuring consistent fit and function across multiple assemblies. The 12-point configuration distributes load more evenly across fastening surfaces, minimizing galling and extending bolt life in corrosive environments—a critical advantage for tactical, marine, and outdoor applications where saltwater or harsh climates accelerate standard hardware degradation.

Armorers, gunsmiths, and field technicians benefit from stocking this kit for rifle builds, optic mount installation, and chassis assembly work where fastener quality directly impacts zero retention and weapon reliability. The five-bolt quantity is ideal for modular platform builds or replacement stock on duty weapons and competition firearms. Installation requires standard 3/8-inch socket or wrench tools; apply appropriate threadlocker compound when assembling critical strike-face components to prevent vibration-induced loosening during sustained firing or high-recoil operations.
