S/S Bolt Kit - 12pt. (5) 1/2-13 x 2.500

The ARP S/S Bolt Kit – 12pt. (5) 1/2-13 x 2.500 is a premium stainless steel fastener set engineered for demanding tactical, military, and firearms applications where corrosion resistance and structural integrity are non-negotiable. This five-piece bolt kit is designed for operators, gunsmiths, and maintenance personnel who require critical hardware that withstands harsh environmental exposure, saltwater environments, and high-stress assembly work. Whether you're building custom rifle platforms, assembling suppressor components, or conducting equipment maintenance in field conditions, precision bolts with superior material properties are foundational to system reliability.

Each bolt in this kit features a 1/2-13 thread specification with a 2.5-inch length and a polished 12-point head design that facilitates secure engagement with standard sockets and allows for precise torque application without rounding. Manufactured from stainless steel and finished to a polished state, these fasteners resist oxidation, corrosion, and galling—critical properties when disassembly and reassembly cycles are frequent or when exposure to moisture, salt spray, or chemical solvents is anticipated. The 12-point head geometry distributes load more evenly across contact surfaces compared to 6-point designs, reducing the risk of fastener damage during high-torque operations typical in tactical hardware assembly.

This bolt kit is ideal for armors, gunsmiths, and military maintenance personnel assembling or servicing suppressors, muzzle devices, rail systems, and modular firearm platforms that demand universal fastener compatibility. The universal design ensures compatibility across multiple applications and platforms without platform-specific limitations. Installation requires standard 3/4-inch sockets; operators should apply appropriate thread-locking compound and torque specifications per manufacturer guidelines for the specific application. Five bolts per kit provide redundancy and allow for multiple component assemblies or replacement stock in field kits and maintenance bags.
