Professional Applications & Engineering Value

This Grade 5 zinc-plated steel locknut delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety risks. The distorted thread technology at the top section creates controlled interference that maintains clamping force even under severe vibration conditions, making it ideal for heavy machinery, automotive assemblies, and construction equipment. The UNF fine thread configuration provides superior load distribution compared to coarse threads, while the zinc plating offers essential corrosion protection in harsh operating environments. With its external hex drive and standard profile, installation and removal remain straightforward using conventional tools, ensuring efficient maintenance cycles without compromising locking performance.

Specification Summary & Compliance

This locknut features precision 7/8"-14 UNF fine threads with Class 2B fit tolerance for reliable engagement, manufactured from Grade 5 medium carbon steel for consistent strength performance. The top lock distorted thread design provides the primary locking mechanism, with dimensions of 1 5/16" width and 13/16" height conforming to standard hex nut profiles. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring adherence to international environmental and safety standards for industrial components.
