Professional Applications & Engineering Value

This M22x1.5mm Class 10 zinc-plated steel locknut delivers critical vibration resistance where conventional fasteners fail. The distorted thread locking mechanism creates permanent friction that prevents loosening under continuous stress, making it ideal for heavy machinery, automotive assemblies, and industrial equipment subject to constant vibration. The fine metric thread with Class 6H precision ensures superior engagement with mating bolts, while the zinc-plated steel construction provides durable corrosion protection in demanding environments. Engineered for external hex drive compatibility, this locknut offers straightforward installation with standard tools, reducing assembly time and maintenance costs in industrial fastening applications.

Specification Summary & Compliance

This metric locknut features M22x1.5mm fine thread with Class 6H thread fit tolerance, ensuring precise dimensional accuracy per metric standards. The distorted top-lock thread design provides reliable locking performance, while the Class 10 strength rating guarantees high mechanical performance. Manufactured from zinc-plated steel with dimensions of 32mm width and 22mm height, this locknut complies with RoHS 3 (2015/863/EU) environmental standards for industrial safety and regulatory requirements.
