- Optimized for fine thread applications with 1.5mm pitch offering superior holding power in precision assemblies
Professional Applications & Engineering Value
This M16 distorted thread locknut delivers critical vibration resistance where conventional fasteners fail. The top lock distorted thread design creates intentional interference that prevents loosening under cyclic loading, making it ideal for automotive components, industrial machinery, and construction equipment. The black phosphate steel construction provides excellent corrosion resistance while maintaining the Class 10 strength rating required for high-stress applications. With fine thread spacing and Class 6H thread fit, these locknuts ensure precise engagement and consistent clamping force, eliminating the need for secondary locking devices and reducing assembly time in production environments.
Specification Summary & Compliance
This metric locknut features M16x1.5mm fine threads with Class 6H thread fit tolerance and standard 24mm width external hex drive. The manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards. The distorted thread locking mechanism provides reliable vibration resistance while maintaining the structural integrity required for Class 10 strength classification in demanding industrial applications.
