Professional Applications & Engineering Value

This 6-32 UNC coarse thread locknut addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and electrical enclosures. The black zinc-plated steel construction provides durable corrosion resistance while the integrated external-tooth lock washer creates positive locking action that withstands sustained vibration and thermal cycling. The Class 2B thread fit ensures consistent engagement with mating components, reducing installation time and preventing cross-threading issues. Engineered for external hex drive compatibility, this locknut delivers reliable performance in maintenance-intensive environments where repeated disassembly is required, making it ideal for conveyor systems, motor mounts, and heavy equipment where vibration resistance is paramount.

Specification Summary & Compliance

This locknut features 6-32 UNC coarse threading with Class 2B fit tolerances, ensuring precise thread engagement and interchangeability. The external hex drive measures 5/16" across flats with a total height of 9/64". Manufacturing complies with industry standards for locknut performance, while material composition and finishing processes adhere to REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance requirements for environmental safety and restricted substance control.
