• Class 2B thread fit guarantees smooth engagement and compatibility with standard 2A external threads, minimizing assembly issues.
• External hex drive design allows for easy tightening with common wrenches, speeding up maintenance and adjustments.
• REACH and RoHS 3 compliance ensures environmental safety and regulatory adherence for global industrial supply chains.
• Compact 5/16" height and 3/4" width offers space-saving benefits without compromising on durability in tight-turnbuckle setups.

Professional Applications & Engineering Value

This Grade 2 steel hex jam nut set is engineered to address common challenges in turnbuckle and tensioning systems, where vibration and load shifts can cause fasteners to loosen. The inclusion of both left-hand and right-hand threaded nuts enables precise adjustment and locking on opposing threads, preventing unintended rotation in dynamic environments. Made from robust steel, the nuts resist wear and corrosion in industrial settings, while the UNC coarse thread design ensures quick, reliable engagement even in high-vibration applications. The external hex drive simplifies installation with standard tools, reducing downtime. Ideal for rigging, construction, and machinery, this set enhances safety and longevity by maintaining tension integrity under stress.

Specification Summary & Compliance

This hex jam nut set adheres to UNC thread standards with a 1/2"-13 coarse thread and Class 2B thread fit for precise dimensional accuracy. Manufactured to Grade 2 strength specifications, it includes one left-hand and one right-hand threaded nut, each measuring 3/4" in width and 5/16" in height. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring it meets environmental and safety standards for industrial use.
