5/16-24 RH Steel Jam Nuts 50pk

The 5/16-24 RH Steel Jam Nuts 50pk from Allstar Performance delivers precision fastening solutions for tactical equipment assembly, mechanical systems, and field repairs where vibration isolation and secure locking are non-negotiable. Jam nuts—also called lock nuts—serve a critical function in military and law enforcement applications where equipment must remain secure under extreme conditions, constant movement, and demanding field use. This 50-pack quantity ensures you maintain adequate inventory for unit-level maintenance, mobile repair kits, and long-term operational readiness without frequent resupply needs.

Manufactured from steel, these right-hand threaded jam nuts feature the standard 5/16-24 metric specification, providing compatible fastening across NATO-standard and domestic tactical platforms. The jam nut design functions by applying a secondary locking nut against a primary fastener, creating mechanical resistance to vibration-induced loosening through friction and deformation—a proven technique employed in aerospace, automotive, and small arms assembly for over a century. Steel construction ensures durability under temperature fluctuation, corrosive environments, and repeated assembly cycles typical of field maintenance protocols and combat equipment reconfiguration.

Armourers, maintenance personnel, and equipment technicians benefit most from maintaining surplus stock of these fasteners for mounting optics, securing rail systems, assembling suppressors, and securing mechanical components on rifles, carbines, and support weapons. Compatibility extends across any platform using 5/16-24 RH threading—common in AR-pattern rifles, pistol-mounted accessories, and modular tactical systems. The compact 4.4 x 2.3 x 4.8-inch pack dimensions and lightweight profile (0.45 lbs) fit seamlessly into maintenance kits, vehicle tool storage, and field repair bags for immediate deployment when equipment requires emergency secured assembly.
