Professional Applications & Engineering Value
This 7/16"-20 UNF steel locknut delivers critical vibration resistance where conventional fasteners fail. The distorted thread top lock technology creates intentional interference that maintains clamping force under extreme conditions, making it ideal for industrial machinery, automotive assemblies, and heavy equipment where vibration-induced loosening compromises safety and performance. The ASTM Grade C material provides the necessary strength for high-load applications while the fine UNF thread offers superior tension control. As an external hex locknut, it ensures compatibility with standard tools for efficient maintenance and assembly operations in manufacturing and repair environments.
Specification Summary & Compliance
This locknut features Class 2B thread fit per UNF standards with 7/16"-20 fine thread configuration and right-hand thread direction. Manufactured to ASTM Grade C specifications for consistent quality and performance. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in industrial applications worldwide.
