Professional Applications & Engineering Value
This M12 flange nut is engineered to solve critical fastening challenges in heavy machinery, automotive, and construction sectors. The black oxide steel material provides excellent corrosion resistance, reducing maintenance needs in exposed or humid conditions. Its 25mm flange diameter acts as an integrated washer, distributing clamp load over a wider area to prevent loosening under vibration and minimize damage to soft materials. The coarse thread with 1.75mm pitch ensures rapid installation and superior resistance to vibrational loosening in dynamic load applications. Manufactured to DIN 6331 specifications, it delivers consistent quality and reliability for industrial flange nut requirements where Class 10 strength is mandatory for safety-critical connections.
Specification Summary & Compliance
This flange nut meets DIN 6331 manufacturing standards with Class 6H thread fit tolerance for precise engagement. The metric coarse thread (M12 x 1.75mm) ensures compatibility with standard components. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
