Professional Applications & Engineering Value

This 3/8"-24 UNF flange lock nut delivers exceptional performance in demanding industrial and aviation applications where vibration resistance is critical. The distorted thread locking technology creates consistent interference fit that maintains clamp load without requiring additional locking elements. Manufactured from cadmium yellow-chromate plated steel, this fastener provides superior corrosion resistance while maintaining electrical conductivity for grounding applications. The integrated 0.62" flange diameter distributes bearing pressure effectively, reducing surface damage and preventing loosening under dynamic loads. Ideal for aviation assemblies, heavy machinery, and precision equipment where reliability cannot be compromised, this MS21042-6 compliant nut ensures consistent performance in the most challenging environments.

Specification Summary & Compliance

This flange lock nut features 3/8"-24 UNF fine threads with Class 3B thread fit for precision engagement, right-hand thread direction, and meets MS21042-6 military specifications. The cadmium yellow-chromate plating provides corrosion protection while maintaining dimensional accuracy. Manufactured to exacting standards with a standard hex profile (7/16" width) and 9/32" height, this nut ensures reliable performance in industrial and aviation applications requiring consistent locking performance and environmental resistance.
