Professional Applications & Engineering Value

This 7/16"-20 UNF locknut with top lock 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 ASTM Grade C strength requirements. The fine thread UNF configuration offers superior clamping force distribution compared to coarse threads, making it ideal for applications requiring precise torque control and sustained bolt tension. The distorted thread locking mechanism creates controlled interference that eliminates the need for secondary locking devices, reducing assembly time and maintenance costs in vibration-prone environments while maintaining full reusability.

Specification Summary & Compliance

This locknut features Class 2B thread fit tolerance per UNF standards, ensuring precise thread engagement and consistent performance. Manufactured to ASTM Grade C strength specifications with dimensions of 11/16" width and 3/8" height. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, containing no restricted substances above threshold limits. Right-hand thread direction with external hex drive provides standard installation compatibility across industrial applications.
