Bolt Kit - 12pt. (5) 3/8-24 x .750

The Bolt Kit - 12pt. (5) 3/8-24 x .750 from ARP is designed for precision fastening in high-performance applications. This five-piece kit is ideal for shooters, gunsmiths, and tactical professionals who require reliable fasteners that maintain clamping force under demanding conditions. Whether assembling a competition build or performing armorer-level repairs, quality bolts are essential for safe and consistent firearm function.

ARP's 12-point bolt design offers superior engagement geometry compared to standard 6-point fasteners, which helps distribute load evenly across the bolt head and reduces the risk of strip-out. The 3/8-24 thread pitch with a length of 0.750 inches is a standard specification for tactical platform construction, ensuring dimensional consistency for regulated assembly and disassembly. These fasteners are manufactured to tight tolerances, providing a proper fit in countersunk or counterbored holes, which is crucial for maintaining accuracy and longevity in precision systems.

This kit is suitable for AR platform builds, optic mount installations, rail systems, and any component assembly requiring 3/8-24 fastening. The five-piece quantity is perfect for typical small builds or as refresh kits for service weapons. Installation requires standard 9/16-inch or appropriately sized hex key tools, ensuring ease of use for professionals and enthusiasts alike.
