Professional Applications & Engineering Value

This M22x2.5 Class 10 locknut delivers critical engineering solutions for industries where vibration-induced fastener failure poses significant risks. The distorted thread locking mechanism creates permanent friction along the bolt threads, effectively resisting rotational forces in heavy machinery, automotive assemblies, and structural applications. Manufactured from black phosphate steel, the nut provides enhanced corrosion resistance while maintaining the mechanical properties required for high-strength fastening. The coarse metric thread design ensures rapid installation and reliable performance in demanding environments, making it ideal for construction equipment, industrial machinery, and transportation systems where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This heavy-duty locknut features M22x2.5 coarse threads with Class 6H thread fit tolerance for precise mating compatibility. The external hex design measures 33mm across flats with a 22mm height profile. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring regulatory compliance for industrial applications. The Class 10 strength rating confirms its suitability for high-stress fastening requirements across various engineering sectors.
