Professional Applications & Engineering Value

This flange lock nut delivers critical vibration resistance where mechanical fasteners face constant dynamic stresses. The zinc-flake-coated steel construction provides exceptional corrosion resistance, making it ideal for outdoor equipment, automotive assemblies, and industrial machinery exposed to environmental challenges. The integrated serrated locking mechanism creates permanent friction against mating surfaces, preventing loosening in high-vibration applications without damaging components. With UNC coarse threads and Class 2B thread fit, this heavy-duty fastener ensures reliable performance in manufacturing, construction, and maintenance operations where vibration-resistant locking solutions are essential for equipment safety and longevity.

Specification Summary & Compliance

This flange lock nut features 5/16"-18 UNC coarse threads with Class 2B thread fit for consistent engagement and proper clearance. The external hex drive (1/2" width) accommodates standard tools while the 43/64" flange diameter provides optimal bearing surface. Manufactured to industry standards with zinc-flake-coated steel for corrosion protection, this component is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility in industrial applications.
