Professional Applications & Engineering Value

This 6-32 UNC flange lock nut delivers exceptional engineering value through its silver-plated A286 stainless steel construction and distorted thread center lock technology. The combination addresses critical industrial challenges where vibration-induced loosening can compromise system integrity. The flange design eliminates the need for separate washers while providing superior load distribution, making it ideal for aerospace assemblies, heavy machinery, and precision equipment where space constraints and reliability are paramount. The coarse thread spacing and Class 3B thread fit ensure rapid installation with minimal cross-threading risk, while the external hex drive facilitates torque application in confined spaces. This MS21043-06 compliant fastener maintains consistent performance in high-stress environments where temperature fluctuations and corrosive elements would degrade ordinary fasteners.

Specification Summary & Compliance

This heavy-duty flange lock nut features precise 6-32 UNC coarse threads with Class 3B thread fit for superior engagement. The distorted thread center lock mechanism provides reliable vibration resistance while maintaining MS21043-06 specification compliance. Manufacturing adheres to strict dimensional tolerances with 3/16" width and 9/64" height for consistent performance. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring safety and regulatory adherence for industrial and aerospace applications.
