1/4-20 x 4.750 12pt Bolt Kit 5pk

The 1/4-20 x 4.750 12pt bolt kit 5pk from ARP is purpose-built for precision fastening in high-stress tactical, law enforcement, and military applications. These bolts are engineered for components that demand uncompromising reliability—from firearm assembly and optic mounting systems to critical load-bearing structural hardware. The five-piece configuration ensures you maintain field-ready inventory without excess bulk, making this kit ideal for armorer kits, maintenance supplies, and tactical load-out builds where fastener redundancy matters.

Each bolt features a 1/4-20 thread pitch—the industry standard for modular firearm components and tactical hardware—with a 4.750-inch length that accommodates through-hole mounting and deep-set assembly configurations. The 12-point head design provides superior torque distribution and reduced fastener rounding compared to six-point alternatives, critical when working with precision-toleranced aluminum and polymer receivers under dynamic conditions. ARP fasteners are manufactured to exacting standards, ensuring consistent thread geometry, head straightness, and material integrity across the entire kit. This level of consistency prevents binding, cross-threading, and premature wear on receiver threads—common failure points in field-deployed equipment.

This bolt kit is essential for armorers, gunsmithing professionals, and military maintenance personnel who service modular systems, quad-rail hand guards, scope mounts, and rail adapters. The 5pk format aligns with standard maintenance rotations and allows proper inventory cycling during field rebuilds. Whether you're performing routine service on patrol rifles, building custom platforms, or maintaining special operations equipment, having precision-grade fasteners on hand prevents mission delays caused by stripped threads or compromised hardware. Pair this kit with thread-locking compound for permanent applications or leave dry for field-adjustable setups where periodic reconfirming is required.
