• Optimized for coarse thread applications with 7/16"-14 UNC threading providing strong holding power in various materials

Professional Applications & Engineering Value

This 7/16"-14 UNC locknut delivers critical vibration resistance where conventional fasteners fail. The distorted thread top lock design creates controlled interference that maintains preload without requiring additional locking devices, simplifying assembly while reducing component count. Manufactured from 18-8 stainless steel, it provides inherent corrosion resistance for outdoor equipment, marine applications, and chemical processing environments where moisture and corrosive agents are present. The external hex drive accommodates standard torque tools for precise installation in confined spaces. With coarse UNC threading, this locknut excels in applications involving softer materials or where rapid assembly is required, making it ideal for heavy machinery, transportation equipment, and structural assemblies subject to dynamic loading conditions.

Specification Summary & Compliance

This locknut features 7/16"-14 UNC coarse threading with Class 2B thread fit for precise engagement with mating components. The distorted thread top lock configuration provides the primary locking mechanism, while the standard hex profile (11/16" width, 3/8" height) ensures compatibility with conventional wrenching tools. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, this fastener meets international environmental standards for industrial applications. The right-hand thread direction and external hex drive style follow established industrial conventions for consistent performance across assembly operations.
