The Bolt Kit - 12pt. (5) 7/16-14 x 2.000 by ARP is a precision fastener set engineered for high-reliability assembly in tactical, military, and performance applications where vibration resistance and structural integrity are non-negotiable. This five-piece kit provides the critical hardware needed to secure critical components in firearms, vehicle mounts, and equipment systems. Whether you're building a duty rifle, assembling tactical accessories, or maintaining armorer-level inventory, these bolts deliver the dependability demanded by law enforcement and military professionals.
Constructed from chromoly steel with black oxide finish, each bolt in this set features a 12-point head geometry that distributes load evenly and resists stripping during installation and repeated assembly cycles. The 7/16-14 thread pitch provides fine threading precision for controlled torque application, while the 2-inch length accommodates standard rail systems, scope mounts, and receiver components. Black oxide coating provides corrosion resistance and a low-reflective profile critical in field conditions. ARP's manufacturing standards ensure dimensional accuracy and material consistency across all five bolts, eliminating the variability of mixed-source hardware.
Armorers, gunsmiths, and tactical equipment specialists rely on this fastener set for mounting optics, rails, and receiver components where thermal cycling and recoil impulse demand reliable clamping force. The 12-point head design pairs well with standard socket and wrench profiles, reducing rounding risk during installation. Compliance with universal fastening standards makes this kit compatible with AR-platform systems, precision rifles, mounting hardware, and modular tactical accessories. For professionals stocking essential inventory or completing critical assembly work, the Bolt Kit - 12pt. (5) 7/16-14 x 2.000 delivers field-proven reliability.
