Jack Bolt Boss Threaded 1in Coarse x 2in Long

The Jack Bolt Boss Threaded 1in Coarse x 2in Long is a precision-engineered fastening component built to meet exacting mil-spec and law enforcement standards. Manufactured by U-B Machine, this threaded bolt serves critical functions in weapons systems, equipment assembly, and tactical platforms where failure is not an option. Whether you're outfitting duty weapons, maintaining field gear, or building precision assemblies, this coarse-threaded fastener delivers the reliability professionals demand in high-stakes environments.

Featuring a 1-inch coarse thread pitch, this bolt provides rapid engagement and superior load-holding capability under recoil, vibration, and thermal stress—critical properties in tactical and military applications. The 2-inch length accommodates standard receiver configurations and component stacking common in AR platforms, suppressors, and modular systems. Coarse threads resist stripping and maintain integrity even when repeatedly cycled, making this fastener ideal for quick-change components that see regular field maintenance. The compact 0.61 lb profile ensures minimal weight penalty while delivering full-strength performance.

LEO armorers, military technicians, and tactical builders rely on properly specified fasteners to ensure weapon system integrity and operator safety. The Jack Bolt Boss Threaded 1in Coarse x 2in Long is compatible with standard receiver threads and mounting blocks across AR-platform rifles, muzzle devices, and accessory rails. When installing or replacing threaded fasteners on duty weapons or precision builds, always verify thread compatibility and apply appropriate threadlocker per manufacturer specifications to prevent loosening under operational stress.
