Professional Applications & Engineering Value

This heavy-duty Class 10 flange nut delivers exceptional engineering value in demanding applications where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides superior corrosion protection for outdoor equipment, agricultural machinery, and industrial assembly lines exposed to moisture and chemicals. The integrated 42.8mm flange acts as a built-in washer, distributing clamping force over a wider area to prevent surface damage and maintain joint integrity under dynamic loads. With its M20 coarse thread and 2.5mm pitch, this metric flange nut enables rapid installation in high-volume production environments while the external hex drive facilitates secure tightening with standard tools. The combination of DIN 6923 and ISO 4161 compliance ensures precise dimensional accuracy and reliable performance in critical connections across automotive, construction, and heavy equipment applications.

Specification Summary & Compliance

This precision-engineered flange nut features M20 thread size with 2.5mm pitch in right-hand coarse thread configuration, manufactured to Class 6H thread fit tolerances for optimal engagement. The component meets rigorous DIN 6923 and ISO 4161 manufacturing standards, ensuring dimensional accuracy with 30mm width, 20mm height, and 42.8mm flange diameter. Compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives confirms environmental responsibility, while the Class 10 strength rating guarantees performance in high-stress applications requiring maximum reliability.
