Bolt Kit - 12pt. (5) 5/16-18 x 2.250

The Bolt Kit - 12pt. (5) 5/16-18 x 2.250 by ARP is a precision fastener set designed for high-performance applications where reliability and structural integrity are essential. This five-piece kit is ideal for law enforcement, military, and tactical equipment builds that require durable hardware capable of withstanding demanding conditions. Whether you're assembling custom weapon platforms, securing optics mounts, or reinforcing protective gear systems, this bolt kit serves as a reliable foundation for equipment that performs under pressure.

Each bolt features a 12-point head design, which efficiently distributes load across fastening surfaces compared to conventional six-point heads. This design reduces the risk of bolt stripping during installation and removal cycles, making it critical for field-maintained equipment. The 5/16-18 thread specification (5/16-inch diameter, 18 threads per inch) provides a medium-coil fastener suitable for precision mechanical assemblies common in tactical platforms and armor systems.

Professionals in weapons manufacturing, plate carrier assembly, and duty optics installation recognize ARP hardware for its reliability and performance. At 2.250 inches in length, these bolts accommodate applications requiring deeper penetration through multiple component layers without needing washers or spacers. The kit's weight of 0.34 lbs makes it field-portable and easy to store in maintenance kits or vehicle emergency packs.
