Professional Applications & Engineering Value

This Class 10 heavy-duty locknut with distorted top lock technology addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and structural applications. The M30x2mm fine metric thread provides superior tension control and seating accuracy compared to coarse threads, while the zinc-plated steel construction offers excellent corrosion resistance in outdoor or chemically aggressive environments. The external hex drive ensures compatibility with standard tools, facilitating efficient installation in confined spaces. Engineered for heavy-duty applications where vibration resistance and long-term reliability are paramount, this locknut maintains clamping force integrity through the distorted thread section that creates consistent friction and prevents rotational movement under dynamic loading conditions.

Specification Summary & Compliance

This metric locknut features precise M30x2mm fine threading with Class 6H thread fit tolerance for optimal engagement. The external hex design measures 46mm across flats with a 30mm height profile. Manufactured to Class 10 strength rating standards with distorted top lock functionality for vibration resistance. Compliant with RoHS 3 (2015/863/EU) environmental regulations and manufactured according to metric threading standards for consistent performance across industrial applications.
