Bolt Kit - 12pt. (5) 5/16-18 x 1.250

The Bolt Kit - 12pt. (5) 5/16-18 x 1.250 by ARP represents precision fastening engineered for high-stress applications where reliability is non-negotiable. This five-piece bolt kit is designed for law enforcement, military, and tactical equipment builders who demand fasteners that maintain integrity under extreme conditions. Whether securing optic mounts, rail systems, or critical component assemblies, these ARP bolts deliver the clamping force and consistency required in field-proven configurations.

Constructed with 12-point socket head geometry, the 5/16-18 x 1.250 specification provides superior engagement and reduced fastener stripping compared to traditional six-point designs—critical when mounting precision optics or accessory rails that demand zero movement during recoil cycles. The 5/16-18 thread pitch ensures adequate tensioning capability while remaining compatible with standard tactical tool kits, and the 1.250-inch length accommodates multi-layer mounting interfaces common in modern rail systems and picatinny adapters. ARP's engineering delivers consistent hardness and thread geometry that resists vibration loosening, a persistent problem in combat environments where equipment must maintain zero shift through thousands of rounds.

Operators working with modular rail systems, scope bases, and accessory mounts will recognize these bolts as essential consumables for reliable system assembly. The five-piece quantity provides sufficient fasteners for complete optic mounting platforms or rail-to-receiver interfaces with spares for maintenance rotations. Installation requires standard metric hex drivers compatible with 12-point socket heads; proper torque sequencing ensures even clamping pressure and maximum recoil stability. Professionals building precision tactical platforms or maintaining issued equipment should maintain this bolt kit in their inventory for rapid repairs and equipment modifications in the field.
