Bolt Kit - 12pt. (5) 8mm x 1.25 x 25mm

The Bolt Kit - 12pt. (5) 8mm x 1.25 x 25mm is a precision fastening solution engineered for tactical weapon systems, AR platforms, and military-grade equipment assembly. Crafted by ARP, a trusted manufacturer in high-performance fasteners, this five-piece bolt kit addresses the critical need for reliable, consistent hardware in mission-critical applications. Whether you're building a custom rifle, performing maintenance on tactical gear, or assembling components that demand uncompromising durability, this bolt kit delivers the fastening integrity that law enforcement and military operators depend on.

Each bolt features a 12-point head geometry, a design choice that provides superior grip surface area and reduces the risk of rounding during installation and removal—critical when working in field conditions or high-stress environments. The 8mm diameter with a 1.25mm pitch thread specification ensures compatibility with standard metric fastening requirements common in precision rifle builds and tactical platforms. The 25mm length positions these bolts as ideal candidates for receiver assembly, action screws, and component mounting applications where precise engagement depth prevents over-torque damage while maintaining full clamping force. ARP's manufacturing standards ensure consistent material composition and dimensional tolerance across all five pieces in the kit.

Operators and gunsmiths building custom AR-15s, AR-10s, or precision bolt-action rifles will find this kit essential for upper and lower receiver assembly, rail mounting, and accessory attachment points. The five-bolt quantity supplies a complete assembly job with minimal waste, making it an economical choice for both single builds and professional gunsmiths who maintain inventory. Installation requires standard metric Allen key or wrench engagement with the 12-point head; always verify thread compatibility with your specific platform before assembly and apply appropriate threadlocker per manufacturer recommendations for permanent installations in recoil-sensitive applications.
