Professional Applications & Engineering Value

This M30 locknut with distorted top-lock threads delivers critical engineering value in applications where vibration-induced loosening compromises safety and performance. The zinc-plated steel construction provides essential corrosion resistance while maintaining the Class 10 strength rating required for heavy machinery, structural assemblies, and industrial equipment. The metric coarse threading (3.5mm pitch) ensures rapid installation and reliable performance in high-vibration environments such as automotive manufacturing, construction equipment, and material handling systems. The external hex drive facilitates straightforward installation with standard tools, while the distorted thread locking mechanism creates consistent friction that resists rotational forces without compromising thread integrity or requiring additional locking components.

Specification Summary & Compliance

This heavy-duty locknut features precision Class 6H thread fit with metric coarse threading (M30x3.5mm) manufactured to exacting dimensional standards. The external hex profile measures 46mm across flats with 30mm height, providing optimal wrench engagement. The product complies with RoHS 3 (2015/863/EU) environmental standards and meets the mechanical properties specified for Class 10 strength classification, ensuring reliable performance in industrial applications requiring maximum vibration resistance and holding power.
