Professional Applications & Engineering Value

This M30 nylon insert lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The zinc-plated steel construction provides essential corrosion protection while maintaining structural integrity under heavy loads. The nylon insert locking mechanism creates consistent friction that prevents loosening from machinery vibration, making it ideal for automotive assemblies, construction equipment, and industrial machinery. With its Class 6H thread fit and metric coarse threading (3.5mm pitch), this locknut ensures precise engagement and reliable performance in high-stress environments where temperature fluctuations up to 220°F may occur. The external hex design facilitates efficient installation and maintenance cycles, reducing downtime in production facilities.

Specification Summary & Compliance

This locknut features M30 metric coarse threading with 3.5mm pitch and Class 6H thread fit tolerance for precision engagement. The external hex drive measures 46mm across flats with 30mm height profile. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring environmental compliance for industrial applications worldwide. The nylon insert locking technology maintains performance within specified temperature ranges while providing consistent vibration resistance throughout the fastener's service life.
