Professional Applications & Engineering Value

This Class 8 steel flange lock nut delivers exceptional engineering value in high-vibration environments where fastener integrity is critical. The serrated locking mechanism beneath the 26mm flange bites into mating surfaces, creating permanent resistance to rotational loosening from machinery vibrations or thermal cycling. Manufactured from metric M12x1.75 coarse thread with Class 6H thread fit, it maintains precise tolerances while allowing rapid installation in automotive assemblies, heavy equipment, and structural frameworks. The integrated flange design eliminates separate washers, streamlining assembly processes while providing superior clamping force distribution. Compliant with DIN 6923 and ISO 4161 standards, this hex flange nut offers reliable performance in manufacturing, transportation, and industrial machinery applications where safety and durability are paramount.

Specification Summary & Compliance

This flange lock nut features M12 coarse thread with 1.75mm pitch and Class 6H thread fit per ISO metric standards. The 18mm width across flats and 12mm height provide standard wrench clearance, while the 1.8mm flange thickness ensures structural integrity. Manufacturing complies with DIN 6923 and ISO 4161 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits.
