Professional Applications & Engineering Value

This M3 metric locknut with external-tooth lock washer addresses critical vibration-induced loosening challenges in industrial equipment and machinery. The 18-8 stainless steel construction provides excellent corrosion resistance for demanding environments including marine, chemical processing, and outdoor applications. The integrated 400 stainless steel washer features precisely engineered teeth that bite into mating surfaces, creating permanent locking action without requiring additional components. This coarse thread metric fastener with 0.5 mm pitch ensures rapid installation in production lines while the Class 6H thread fit guarantees consistent torque values and reliable performance in automotive assemblies, electrical enclosures, and mechanical systems subjected to continuous vibration and thermal cycling.

Specification Summary & Compliance

This M3 x 0.5 mm locknut features Class 6H thread tolerance per metric standards with right-hand coarse threading for optimal engagement. The assembly combines a standard hex nut profile (5.5mm width, 3.3mm height) with an external-tooth lock washer (6.5mm OD) manufactured from 400 series stainless steel. The fastener system is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications worldwide.
