Professional Applications & Engineering Value

This M8 flange lock nut delivers critical engineering solutions where vibration-induced loosening compromises assembly integrity. The serrated locking mechanism creates permanent friction against mating surfaces, making it ideal for automotive components, heavy machinery, and structural frameworks exposed to constant motion. Manufactured from zinc yellow-chromate plated steel, it provides dual protection against corrosion while maintaining Class 8 strength under extreme tension. The integrated 17.9mm flange distributes load stress efficiently, preventing surface damage and reducing total component count. With metric coarse threading and standardized external hex drive, it ensures compatibility across European and international equipment designs requiring reliable, maintenance-free fastening.

Specification Summary & Compliance

This flange lock nut maintains Class 6H thread fit tolerance with M8 x 1.25mm coarse right-hand metric threading. Manufacturing complies with DIN 6923 and ISO 4161 specifications, ensuring dimensional accuracy across flange diameter (17.9mm), thickness (1.2mm), and hex width (13mm). The zinc yellow-chromate plating meets RoHS and REACH environmental standards while providing corrosion resistance. Class 8 strength certification guarantees performance in accordance with international mechanical property requirements for industrial fasteners.
