Professional Applications & Engineering Value
This 10-32 UNF flange locknut is engineered to address common challenges in aerospace and industrial assemblies, where vibration and corrosion can compromise integrity. The silver-plated A286 stainless steel construction offers excellent strength and oxidation resistance at elevated temperatures, while the distorted thread center lock mechanism securely maintains clamp load without requiring additional locking elements. Its fine thread and Class 3B fit provide tight tolerances, reducing the likelihood of fastener failure in dynamic loads. By integrating the flange, it simplifies installation and enhances joint stability, making it a reliable choice for engines, machinery, and electronic enclosures that demand long-term durability and regulatory compliance.
Specification Summary & Compliance
This flange locknut features a 10-32 UNF fine thread with Class 3B thread fit for high precision, and adheres to MS21043-3 standards. Key dimensions include a flange diameter of 0.33", width of 1/4", and height of 3/16". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial and aerospace applications.
