Bolt Kit - 12pt. (5) 8mm x 1.25 x 30mm

The Bolt Kit - 12pt. (5) 8mm x 1.25 x 30mm by ARP is a precision fastening solution engineered for demanding tactical, military, and firearms applications where reliability under stress is non-negotiable. This five-piece bolt set is designed for operators and gunsmiths who require OEM-grade hardware for AR platform builds, optic mounts, accessory rails, and critical assembly work. Whether you're performing a complete rifle build or replacing worn fasteners in field-deployed equipment, these bolts deliver the dependable clamping force and material integrity that experienced professionals demand.

Each bolt in this kit features a 12-point head design that accepts both standard hex wrenches and 12-point sockets, reducing the risk of fastener rounding during installation and removal—a critical concern in low-light field conditions. Manufactured from chromoly steel and finished in black oxide, these 8mm x 1.25 thread bolts provide superior fatigue resistance and corrosion protection compared to standard grade hardware. The 30mm length suits a wide range of mounting applications, from picatinny rail attachments to optic base installation, while the 8mm diameter and 1.25 pitch thread accommodate standard tactical component specifications used across military and law enforcement platforms.

Tactical professionals, gunsmiths, and military armorers benefit most from this versatile bolt kit because it eliminates the need for sourcing individual fasteners for common build tasks. The five-piece set ensures you maintain spares for field repairs or complete a typical optic mounting project without surplus inventory. Installation is straightforward: use appropriate torque specifications for your specific application—typically 40–60 inch-pounds for optic bases—and verify thread engagement before final tightening. Compatible with any AR-pattern firearm, precision rifle, or tactical accessory system that uses standard 8mm x 1.25 metric fasteners.
