Professional Applications & Engineering Value

This M12 locknut with distorted center lock technology provides critical vibration resistance in demanding applications where loosening under dynamic loads poses significant safety and performance risks. The zinc-plated steel construction offers durable corrosion protection while maintaining the Class 8 strength rating required for heavy machinery, automotive assemblies, and structural frameworks. The fine 1.5mm pitch metric threads create increased thread engagement surface area, distributing load more effectively than coarse threads and providing superior resistance to back-off in high-vibration environments. Engineered with Class 6H thread fit precision, this external hex locknut ensures consistent performance across production runs while the standard 19mm hex profile allows for efficient installation with common industrial tools.

Specification Summary & Compliance

This metric locknut features M12x1.5mm fine threads with Class 6H thread fit tolerance and right-hand thread direction. The distorted thread locking type utilizes center lock technology for vibration resistance. Dimensions include 19mm width across flats and 10mm height. Manufactured to Class 8 strength rating standards and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and restricted substances.
