Professional Applications & Engineering Value
This zinc-plated steel flange lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The serrated locking mechanism creates permanent resistance to rotational loosening, making it ideal for machinery, automotive assemblies, and equipment subjected to constant motion or impact. The UNF fine thread configuration (5/16"-24) provides superior clamping force distribution compared to coarse threads, while the integrated 43/64" flange eliminates the need for separate washers, reducing assembly time and potential failure points. Engineered with Class 2B thread fit, this external hex drive nut ensures consistent torque values and reliable performance in high-vibration environments where standard nuts would fail.
Specification Summary & Compliance
This flange lock nut features 5/16"-24 UNF fine threads with Class 2B thread fit per ASME/ANSI standards, ensuring precise dimensional accuracy and compatibility. The 43/64" flange diameter and 0.1" thickness provide optimal bearing surface, while the external hex drive (1/2" width) accommodates standard wrenching tools. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, confirming the absence of restricted substances for global industrial applications.
