Professional Applications & Engineering Value

This A286 stainless steel flange lock nut with distorted thread technology addresses critical challenges in aerospace and industrial applications where vibration-induced loosening can compromise system integrity. The center lock distorted thread design creates consistent interference along the mating thread, providing reliable vibration resistance without compromising the Class 3B thread fit precision. The integrated flange distributes clamping force over a wider surface area (0.62" diameter), reducing stress concentrations and preventing surface damage. Manufactured from A286 stainless steel, this 3/8"-24 UNF fine thread nut maintains mechanical properties at elevated temperatures, making it ideal for engine components, structural assemblies, and critical machinery where failure is not an option. The included lubricant ensures proper installation torque values are achieved while minimizing the risk of galling in stainless-to-stainless connections.

Specification Summary & Compliance

This flange lock nut features 3/8"-24 UNF fine threads with Class 3B thread fit precision and right-hand thread direction. The external hex drive (7/16" width) and 9/32" height provide standard tool compatibility. Manufactured to NAS1291C6M specifications with center lock distorted thread technology, the nut ensures reliable performance in demanding applications. Compliance includes REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, confirming adherence to current regulatory requirements for hazardous substance restrictions.
