Professional Applications & Engineering Value

This M3 locknut with external-tooth lock washer provides engineered solutions for vibration-prone applications where fastener integrity is critical. The zinc-plated steel construction offers dual protection against corrosion while maintaining the Class 8 strength required for heavy-duty machinery, automotive assemblies, and industrial equipment. The integrated lock washer creates permanent resistance to rotational forces, eliminating the need for additional locking components and reducing assembly time. With metric coarse threading and Class 6H thread fit, this locking nut ensures precise engagement while preventing cross-threading issues common in high-volume production environments. Ideal for applications requiring repeated disassembly and reassembly without performance degradation.

Specification Summary & Compliance

This metric hex locknut features M3 x 0.5 mm coarse threading with Class 6H thread fit tolerance, ensuring compatibility with standard metric bolts. The 5.5 mm width and 3.3 mm height provide compact dimensions for space-constrained applications. Manufactured to Class 8 strength standards with right-hand thread direction and external hex drive style. Fully compliant with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted substances for industrial safety requirements.
