Maxwell Bolt - Hex HD 5/16" UNC x 1-1/2"

The Maxwell Bolt - Hex HD 5/16" UNC x 1-1/2" is a precision fastener engineered for demanding tactical and military applications where reliability is non-negotiable. This hex head cap screw serves as a critical structural component in weapon systems, load-bearing equipment, and mission-critical gear assembly. Whether you're securing optic mounts, rail systems, or armor plate carriers, this bolt delivers the tensile strength and corrosion resistance required in field conditions where equipment failure is not an option.

Manufactured to Maxwell's exacting standards, this hex HD bolt features a 5/16-inch diameter with UNC (Unified National Coarse) threading and a 1-1/2-inch length, providing sufficient engagement depth for secure fastening without over-extension. The hex head design allows for reliable torque application using standard wrenches or hex drivers, ensuring consistent clamping force across repeated deployment cycles. The hardened steel construction resists vibration-induced loosening and maintains structural integrity under dynamic loads—critical for rifle-mounted accessories, tactical rails, and equipment that experiences constant field stress.

This bolt is ideal for armourers, gunsmiths, and tactical equipment technicians assembling or maintaining firearms and accessories. The 5/16" UNC specification is standard across military-grade rail systems, Picatinny mounts, and specialized mounting hardware. Its lightweight profile (0.1 lbs) makes it suitable for weight-critical applications where every ounce matters, while the compact 1-1/2-inch length ensures compatibility with shallow-threaded receptacles common in modern tactical platforms. Stock this fastener for maintenance kits, equipment repairs, and builds requiring NATO-standard specifications.
