Bolt Kit - 12pt. (5) 1/4-20 x .515

The Bolt Kit - 12pt. (5) 1/4-20 x .515 from ARP is a precision fastener set engineered for tactical weapons systems, optics mounts, and equipment assembly where chromoly strength and reliability are non-negotiable. This five-piece kit delivers the fastening integrity demanded in law enforcement and military applications where component security directly impacts operational safety. Whether securing rail systems, mounting accessories, or assembling critical gear components, this bolt kit provides the redundancy and performance required in high-stakes environments.

Each bolt in this set features a 1/4-20 thread pitch with a 0.515-inch length, specifically designed for applications requiring precise fit without excess material that could interfere with tight installations. The 12-point head geometry distributes load evenly across mounting surfaces while the chromoly construction delivers superior tensile strength compared to standard steel, resisting vibration loosening and stress failure under recoil and environmental cycling. Black oxide coating provides corrosion resistance and a professional tactical appearance while minimizing light reflection—critical for mission-focused equipment. The universal compatibility makes these bolts essential backup fasteners for field repair kits and equipment maintenance protocols.

Tactical professionals, armorers, and military mechanics depend on ARP fasteners for their proven performance in extreme conditions. This kit suits scope base installation, picatinny rail assembly, tactical accessory mounting, and any application where 1/4-20 fastening is specified in equipment manuals or system designs. The compact 0.12-pound weight makes this kit fieldable in maintenance kits, range bags, and emergency repair loadouts. Keeping ARP fasteners on hand ensures mission continuity when standard hardware fails or when original fasteners require replacement in the field.
