Professional Applications & Engineering Value

This 5/16"-24 UNF locknut with distorted thread technology addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment. The zinc-plated steel construction provides essential corrosion resistance while maintaining the ASTM Grade C strength rating for high-stress applications. The top lock distorted thread design creates permanent friction along the mating surface, eliminating the need for secondary locking devices and reducing assembly time. Engineered with UNF fine threads, this fastener delivers superior clamp load distribution and precision alignment in critical joints where vibration resistance and reliability are paramount for operational safety and reduced maintenance downtime.

Specification Summary & Compliance

This locknut features Class 2B thread tolerance for precise fitment and consistent performance across applications. Manufactured to UNF (Unified National Fine) thread standards with 5/16"-24 thread size, the nut ensures compatibility with standard mating components. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, meeting the latest substance restriction requirements. With dimensions of 1/2" width and 17/64" height, this ASTM Grade C locknut provides reliable performance while adhering to industry-recognized manufacturing specifications and quality standards.
