Professional Applications & Engineering Value

This 6-32 UNC coarse thread locknut delivers critical vibration-resistant fastening solutions for industrial equipment, automotive assemblies, and machinery where secure locking performance is paramount. The zinc-plated steel construction provides essential corrosion protection while maintaining Grade 2 strength requirements. The distorted top lock thread design creates consistent interference that prevents back-off in high-vibration environments, eliminating the need for secondary locking devices. With external hex drive compatibility, installation and maintenance are streamlined using standard tools. The coarse thread pitch ensures rapid assembly while the Class 2B thread fit guarantees proper engagement with mating components, making this distorted thread locknut ideal for production lines and field service applications requiring reliable, reusable locking solutions.

Specification Summary & Compliance

This locknut features 6-32 UNC coarse threads with Class 2B thread fit tolerance for optimal assembly clearance. The distorted top lock thread design conforms to industry locking standards while the external hex drive (5/16" width) and 7/64" height provide standardized installation dimensions. Manufactured from zinc-plated steel with Grade 2 strength classification, the component is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for use in global industrial markets.
