Professional Applications & Engineering Value

This zinc-plated steel locknut with distorted thread technology addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and structural frameworks. The top lock design creates controlled resistance at the thread interface, effectively maintaining clamp load under dynamic conditions where conventional nuts would fail. Engineered with UNC coarse threading and Class 2B fit, this external hex locknut delivers predictable installation torque and reliable performance across temperature variations. The combination of ASTM Grade C material strength and corrosion-resistant zinc plating ensures long-term reliability in harsh operating environments, making it ideal for heavy equipment, conveyor systems, and manufacturing applications where vibration resistance is paramount.

Specification Summary & Compliance

This locknut features precise 3/8"-16 UNC coarse threading with Class 2B thread fit tolerance for consistent engagement. Manufactured to ASTM Grade C specifications for mechanical properties and dimensional accuracy. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental safety standards are met. Standard dimensions include 9/16" width and 21/64" height with right-hand thread direction for conventional installation.
