Professional Applications & Engineering Value
This 6-32 UNC zinc-plated steel locknut with integrated spring lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and electrical enclosures. The combination of coarse thread spacing and Class 2B thread fit ensures rapid installation while maintaining precise tolerances for repeated disassembly and reassembly cycles. The external hex drive configuration provides superior torque transmission, making it ideal for high-vibration environments where traditional fasteners fail. The zinc plating creates a sacrificial barrier against corrosion, extending service life in demanding applications while the spring steel washer maintains constant preload, eliminating the need for additional locking components and reducing assembly time.
Specification Summary & Compliance
This heavy-duty locknut features 6-32 UNC coarse threads with Class 2B thread fit tolerances, right-hand thread direction, and standard 5/16" width with 9/64" height. Manufactured from zinc-plated steel with a steel spring lock washer (0.328" OD), the fastener complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring suitability for regulated industrial applications worldwide.
