S/S Bolt Kit - 12pt. (5) 1/2-20 x 2.250

The ARP S/S Bolt Kit – 12pt. (5) 1/2-20 x 2.250 is a precision fastener set engineered for demanding tactical, military, and civilian applications where reliability under load is non-negotiable. This five-piece stainless steel bolt kit delivers the corrosion resistance and structural integrity required in harsh field environments, whether you're assembling upper receiver components, securing rail systems, or building custom tactical platforms. Built to ARP's exacting standards, these bolts ensure consistent performance in high-stress scenarios where fastener failure is simply not an option.

Each bolt in this kit features a robust 1/2-20 thread pitch with a 2.250-inch length, sized for precision mounting applications across modern tactical platforms. The 12-point head design provides multiple engagement angles, reducing fastener rounding and ensuring tool grip that holds up through repeated assembly and disassembly cycles—critical when field maintenance or reconfiguration occurs under pressure. Machined from premium stainless steel with a polished finish, these bolts resist oxidation, salt-air corrosion, and thermal cycling that would compromise lesser fasteners. The universal design makes this kit adaptable across AR-platform builds, precision rifle systems, and universal tactical mounting requirements.

Operators, gunsmiths, and armors rely on ARP bolt kits for upper assembly work, optic mount installation, and rail system attachment where torque retention and fastener security directly impact weapon reliability. The five-bolt quantity covers multiple build projects or replacement needs across a tactical inventory. Installation is straightforward—apply appropriate thread-locking compound if operating in vibration-heavy environments, then torque to specification for your particular application. Compatible with any platform requiring 1/2-20 fastening, this kit represents the professional-grade fastener choice for those who understand that every component in the firing chain matters.
