Professional Applications & Engineering Value

This 3/4"-16 UNF locknut delivers exceptional engineering value through its distorted thread locking mechanism and zinc-plated steel construction. The top lock distortion creates consistent friction along the thread engagement, effectively countering vibration-induced loosening in heavy machinery, automotive assemblies, and industrial equipment. The fine UNF thread provides superior clamping force distribution while the external hex drive ensures compatibility with standard tools for efficient maintenance. Manufactured from ASTM Grade C steel, this locknut maintains its mechanical properties under dynamic loads, making it ideal for applications where safety and reliability are paramount. The combination of distorted thread technology and corrosion-resistant zinc plating addresses common failure points in demanding environments, extending service intervals and reducing maintenance costs.

Specification Summary & Compliance

This locknut features UNF 3/4"-16 fine threads with Class 2B thread fit for precise engagement, manufactured to ASTM Grade C strength requirements. The external hex drive measures 1 1/8" across flats with a 41/64" height profile. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining high performance standards for industrial fastening applications.
