The ARP S/S Bolt Kit - 6pt. (5) 5/16-18 x 1.250 is a professional-grade stainless steel fastener set engineered for tactical equipment assembly, motorsport builds, and precision firearm component installation. This five-piece kit delivers the reliability demanded by law enforcement armorers, military technicians, and competitive shooters who cannot tolerate fastener failure under stress. Whether you're assembling AR platform uppers, securing optic mounts, or replacing worn bolts in precision equipment, this kit provides the corrosion-resistant foundation your build requires.
Each bolt in this set features a 5/16-18 thread pitch with a 1.250-inch length and 3/8-inch hex head, machined to ARP's exacting specifications for repeatable fit and finish. The polished stainless steel construction resists corrosion in harsh field conditions while maintaining full magnetic properties for ferrous tool compatibility. The 6-point hex geometry distributes load evenly across fastener walls, reducing stripping risk during installation and removal—a critical advantage in tactical platforms where repeated maintenance cycles are routine. At just 0.23 lbs for the complete set, these bolts add minimal weight while providing maximum tensile strength for load-bearing applications.
This bolt kit suits armorers building custom upper receivers, technicians servicing precision equipment, and shooters replacing factory fasteners with corrosion-resistant alternatives. The universal design integrates seamlessly into AR platform builds, optic mounting systems, and aftermarket component installation where 5/16-18 threading is specified. Five bolts per kit provide redundancy for multi-component jobs or allow inventory for future builds. Proper torque specifications and thread-locking compound application ensure maximum performance in high-recoil or vibration-prone environments. For demanding applications requiring proven reliability, ARP's S/S Bolt Kit delivers the fastening integrity that separates properly built equipment from field failures.
