Professional Applications & Engineering Value

This M3 metric locknut delivers critical vibration-resistant performance for demanding industrial applications where loosening under dynamic loads is a major concern. The Flex-Top locking design creates consistent radial pressure along the Class 6H thread fit, maintaining clamp force without damaging mating threads. Manufactured from 316 stainless steel, it provides superior corrosion resistance in chemical processing, marine, and food processing equipment where moisture and aggressive media are present. The external hex drive enables high-torque installation with standard tools, while the coarse metric threading ensures rapid assembly in production environments. This combination of locking reliability and material durability makes it ideal for machinery, automotive subsystems, and electronic enclosures subject to continuous vibration.

Specification Summary & Compliance

This locknut features M3 x 0.5mm coarse metric threading with Class 6H thread fit tolerance for precision engagement. The standard hex profile measures 5.5mm across flats with 4.5mm height. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances. The right-hand thread direction and external hex drive conform to international metric fastener standards for compatibility with existing tooling and components.
