Professional Applications & Engineering Value

This M12 flange lock nut delivers critical vibration resistance in high-stress environments where conventional fasteners fail. The nylon insert locking mechanism creates consistent friction against bolt threads, eliminating the need for additional locking devices while maintaining Class 10 strength. The integrated 26mm flange distributes clamping force over a wider surface area, reducing point loading and preventing material deformation in assembled components. Manufactured from zinc plated steel with precision metric fine threads, this DIN 6926 compliant fastener provides reliable performance in automotive assemblies, industrial machinery, and equipment manufacturing where vibration-induced loosening poses significant operational risks.

Specification Summary & Compliance

This flange lock nut features M12x1.5 fine thread with Class 6H thread fit tolerance and right-hand thread direction. Manufactured to DIN 6926 standards with Class 10 strength rating, 18mm width, and 16.1mm height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
