S/S Bolt Kit - 6pt. (5) 1/2-13 X 1.750

The ARP S/S Bolt Kit – 6pt. (5) 1/2-13 X 1.750 is a professional-grade fastener assembly designed for tactical weapon systems, precision machinery, and structural applications where corrosion resistance and load-bearing reliability are non-negotiable. This five-piece stainless steel bolt set addresses the critical need for rust-proof, maintenance-free hardware in high-moisture environments—whether deployed in coastal operations, vehicle platforms, or long-term field storage. Built to ARP's exacting standards, these bolts serve law enforcement, military, and civilian tactical professionals who demand components that won't degrade under harsh conditions.

Each bolt in this kit features a 1/2-13 thread pitch with a 1.750-inch length and a robust 9/16-inch hex head, enabling secure installation using standard or metric wrenches and impact tools common in armorer kits. The polished stainless steel construction provides superior corrosion resistance compared to standard zinc-plated fasteners, eliminating the risk of seizing or galling in salt spray, humidity, or temperature cycling. The six-point head design distributes load more evenly than twelve-point alternatives, reducing fastener rounding and ensuring repeatable torque specifications critical for weapon reliability and zero retention on optics, rails, and accessories.

Armorers, gunsmiths, and tactical equipment specialists will recognize this bolt kit as essential inventory for upper receiver builds, free-float rail installations, and optic mounting systems where thread stripping or fastener failure directly impacts mission capability. The universal design accommodates AR-15/AR-10 platforms, precision rifles, and modular weapon systems requiring 1/2-13 fastening. For operators maintaining gear in field conditions or storing equipment for extended periods, stainless steel hardware eliminates corrosion concerns and reduces preventive maintenance cycles, extending component life and ensuring readiness when it matters most.
