S/S Bolt Kit - 6pt. (5) 5/16-24 x .750

The S/S Bolt Kit - 6pt. (5) 5/16-24 x .750 from ARP is a precision fastener assembly engineered for high-performance firearm builds, competition platforms, and duty-grade tactical systems. This six-point bolt kit addresses a critical need in the firearms community: reliable, corrosion-resistant fasteners that maintain structural integrity under cyclic stress and harsh field conditions. Whether you're assembling an AR platform, installing optic mounts, or securing precision components, this stainless steel solution delivers the dependability demanded by law enforcement, military, and competitive shooters.

Constructed from stainless steel, this five-piece bolt kit features metric 5/16-24 threads with a 0.750-inch length, sized for precision applications requiring secure clamping without over-torque risk. The six-point head design reduces cam-out during installation—a critical advantage when working with hex-socket tools in tight mounting spaces typical of modern firearms accessories. Stainless construction resists corrosion, salt-air degradation, and chemical exposure, ensuring fasteners remain serviceable across multiple deployment cycles and environmental conditions. The compact 3.9 x 0.7 x 5.85-inch package weighs just 0.19 lbs, making these bolts ideal for weight-critical builds while maintaining the material integrity needed for load-bearing applications.

Operators and gunsmiths rely on ARP fasteners for critical assemblies where failure is not an option—rail systems, scope base mounting, handguard attachment, and suppressor indexing. Five bolts per kit provide redundancy for multi-point secure installations or allow stocking across several weapon systems. Installation requires standard metric hex tools (typically 5/32-inch); ensure proper torque sequencing to distribute clamping load evenly. Compatible with all AR platforms, precision rifle builds, and tactical carbines featuring metric hardware patterns. For anyone serious about reliability and longevity in demanding environments, this bolt kit represents the precision-grade hardware standard upheld by professional armorers and tactical operators.
