Professional Applications & Engineering Value

This M4 x 0.7 mm DIN 6923 flange lock nut delivers exceptional engineering value in demanding applications where vibration-induced loosening poses significant reliability concerns. The serrated locking mechanism creates permanent resistance to rotational forces, making it ideal for automotive assemblies, machinery frames, and electrical enclosures subject to constant motion. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining mechanical strength, particularly valuable in chemical processing, marine, and food processing equipment. The integrated 10 mm flange diameter distributes clamping pressure evenly, preventing surface damage and maintaining joint integrity. As a metric coarse thread fastener with external hex drive, it offers quick installation while the Class 6H thread fit ensures precise engagement without cross-threading risks in high-volume production environments.

Specification Summary & Compliance

This flange lock nut features M4 x 0.7 mm metric coarse threading with Class 6H thread fit tolerance per ISO standards, ensuring precise dimensional accuracy. Manufactured to DIN 6923 specifications with right-hand thread direction, it maintains 7 mm width across flats and 4.65 mm height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for industrial fastener applications.
