Professional Applications & Engineering Value

This 5/16"-24 UNF stainless steel locknut is engineered to address critical challenges in industrial settings where vibration and dynamic loads compromise fastener integrity. The distorted center lock design creates consistent interference along the fine UNF threads, effectively resisting loosening in machinery, automotive assemblies, and structural applications. Made from 18-8 stainless steel, it offers exceptional resistance to corrosion and oxidation, extending service life in demanding environments like marine, chemical processing, and outdoor equipment. The Class 2B thread fit ensures reliable engagement with mating components, reducing the risk of assembly errors and maintenance downtime. Ideal for use in vibration-prone systems, this locknut provides long-term security without the need for additional locking devices, streamlining installation and reducing total cost of ownership.

Specification Summary & Compliance

This locknut features a 5/16"-24 UNF fine thread with Class 2B thread fit for precise dimensional accuracy and smooth mating.
