The S/S Bolt Kit - 6pt. (5) 1/4-20 x 3.500 by ARP is a professional-grade fastener solution engineered for high-reliability applications in tactical, military, and law enforcement equipment assembly. This stainless steel bolt kit addresses the critical demand for corrosion-resistant hardware in demanding field environments where standard fasteners fail under salt exposure, moisture, and extreme temperature cycling. Built for operators and armorsmiths who refuse compromise on component integrity, this five-piece kit delivers the redundancy and durability required for mission-critical systems.
Each bolt in this kit features a 1/4-20 thread pitch with a 3.500-inch length, precision-machined to exacting tolerances that ensure consistent fit and function across multiple reassemblies. The six-point head design—standard in professional fastener applications—provides superior load distribution and reduced stress concentration compared to hex alternatives, critical when securing components subject to vibration and recoil impulse. Stainless steel construction offers inherent corrosion resistance without sacrificing tensile strength, making these bolts suitable for both indoor and field-deployed tactical systems, ammunition storage configurations, and vehicle-mounted hardware where rust and material degradation are operational hazards.
Armorsmiths, gunsmiths, and tactical equipment manufacturers depend on precision fasteners like this S/S Bolt Kit when building or maintaining weapon systems, modular platforms, and load-bearing gear. The 1/4-20 specification aligns with standard tactical rail systems, mounting interfaces, and equipment attachment points found across AR platforms, scope bases, and sling mounting systems. Whether replacing worn fasteners in field repairs, building a complete assembly, or stocking a professional maintenance kit, the five-bolt configuration provides immediate operational capability with spare components for redundancy. Inspect and apply appropriate thread-locking compound during installation to ensure permanent retention under field conditions.
