Professional Applications & Engineering Value
This 5/16"-24 UNF flange locknut delivers critical performance where vibration resistance and corrosion protection are paramount. The silver-plated A286 stainless steel construction provides exceptional strength at elevated temperatures while the distorted thread center lock mechanism maintains clamp force under extreme dynamic loads. Engineered specifically for aerospace applications and heavy machinery, the integrated flange design with 0.52" diameter provides superior bearing surface distribution, reducing stress concentrations and preventing surface damage. The Class 3B thread fit ensures precise engagement with mating components, while the external hex drive facilitates installation in confined spaces. This combination of features makes it ideal for critical assemblies where reliability cannot be compromised.
Specification Summary & Compliance
This flange locknut features 5/16"-24 UNF fine threads with Class 3B thread fit precision and right-hand thread direction. Manufactured to MS21043-5 specifications with a standard hex profile, 3/8" width, and 17/64" height. The flange measures 0.52" in diameter with 0.04" thickness. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring regulatory adherence for industrial and aerospace applications.
