- Corrosion-resistant black-oxide steel provides durable protection in demanding industrial environments
- Quick installation with standard external hex drive and UNC coarse threads for faster assembly
- Precision thread fit with Class 2B tolerance ensuring reliable engagement and consistent performance
- Wide compatibility with right-hand UNC coarse thread systems commonly used in industrial equipment
- Regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
This black-oxide steel flange lock nut delivers critical vibration resistance in high-stress applications where fastener integrity is paramount. The serrated locking design creates permanent friction against mating surfaces, eliminating the need for additional locking components in automotive assemblies, machinery frames, and structural connections. The UNC coarse thread profile ensures rapid installation while maintaining Class 2B thread fit precision for consistent clamping force. The integrated 19/32" flange distributes load across wider surface areas, preventing joint fatigue in sheet metal, brackets, and equipment mounting points. Engineered for industrial environments requiring vibration-resistant fasteners that maintain tension through thermal cycling and mechanical stress.
Specification Summary & Compliance
Manufactured to precise dimensional standards including 1/4"-20 UNC coarse thread with Class 2B thread fit tolerance for reliable engagement. Features standard external hex drive (7/16" width) and 15/64" height profile. The black-oxide steel construction meets industry specifications for corrosion resistance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains.
