Bolt Kit - 12pt. (5) 7/16-20 x 1.000

The Bolt Kit - 12pt. (5) 7/16-20 x 1.000 from ARP delivers critical fastening solutions for tactical platforms, engine builds, and precision equipment where load retention and reliability are non-negotiable. Designed for professionals in law enforcement, military operations, and performance motorsports, this five-piece bolt kit addresses the fastening demands of high-stress applications where standard hardware cannot be trusted. Whether securing upper receivers, optic mounts, or engine internals, ARP fasteners have become industry standard for operators who require repeatability and zero tolerance for failure.

Each bolt in this kit features a 12-point head geometry that distributes clamping force more evenly than traditional six-point fasteners, reducing the risk of stripping or rounding during installation and removal cycles common in field maintenance environments. The 7/16-20 thread specification (7/16-inch diameter with 20 threads per inch) and 1.000-inch length provide precise fit for standard AR platform receivers, accessories mounts, and modular tactical systems requiring consistent preload and tensioning. ARP's proprietary manufacturing process ensures uniformity across all five pieces, critical for applications where bolt-to-bolt consistency prevents differential wear and maintains structural integrity under recoil impulse and thermal cycling.

This bolt kit is essential for armorer-level maintenance, custom build projects, and equipment overhauls where OEM hardware replacement is required to maintain factory specifications and warranty compliance. Tactical professionals, gunsmiths, and precision shooters rely on ARP fasteners to eliminate variables in critical assembly points, ensuring that upper and lower receiver unions, rail systems, and accessory mounts hold zero under sustained fire and dynamic movement. The compact five-piece quantity makes this ideal for maintaining a standard rifle or completing a dedicated build, with spare bolts on hand for field replacement without compromising mission readiness.
