Professional Applications & Engineering Value
This M22x1.5mm Class 10 metric locknut delivers critical vibration resistance in demanding industrial environments where mechanical stress and constant motion threaten fastener integrity. The distorted thread locking mechanism creates intentional interference that prevents loosening under dynamic loads, making it ideal for heavy machinery, automotive assemblies, and construction equipment. Manufactured from black phosphate steel, the nut provides excellent corrosion resistance while maintaining the structural integrity required for Class 10 strength rating applications. The fine thread spacing and Class 6H thread fit ensure precise engagement with mating components, eliminating play and maintaining clamping force in high-vibration scenarios where standard nuts would fail.
Specification Summary & Compliance
This locknut features M22x1.5mm metric fine threads with Class 6H thread fit tolerance and Class 10 strength rating. The external hex drive measures 33mm across flats with a 22mm height profile. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring suitability for industrial applications worldwide. The distorted thread locking mechanism conforms to top-lock design principles for reliable vibration resistance.
