• Long-lasting corrosion protection provided by zinc-plated steel construction in harsh environments
• Reliable thread engagement ensured by Class 6H thread fit for consistent fastening performance
• Easy installation and removal with standard 24mm external hex drive using common tools
• Industry-standard compatibility with M16x2 mm coarse thread components and metric fastening systems
• Environmental compliance assurance meeting RoHS 3 standards for responsible manufacturing

Professional Applications & Engineering Value

This M16 top lock nut delivers critical vibration-resistant performance in demanding industrial settings where constant motion and stress would compromise standard fasteners. The distorted thread locking mechanism creates permanent friction that prevents loosening under dynamic loads, making it ideal for heavy machinery, automotive assemblies, and structural applications. Manufactured from zinc-plated steel, it provides excellent corrosion resistance while maintaining the Class 10 strength rating required for high-torque applications. The metric coarse threading ensures quick installation and reliable performance in vibration-prone environments, reducing maintenance frequency and preventing equipment downtime in industrial operations.

Specification Summary & Compliance

This heavy-duty locknut features precise M16x2 mm coarse threading with Class 6H thread fit tolerance for consistent engagement. The external hex drive (24mm width) and 16mm profile comply with metric standards for industrial fastening systems. Manufacturing follows industry specifications for distorted top lock thread design and meets RoHS 3 (2015/863/EU) compliance requirements for environmental safety. The Class 10 strength rating certifies its performance in high-stress applications according to international metric fastener standards.
