Professional Applications & Engineering Value

This Class 10 heavy-duty flange nut is engineered to address critical challenges in industrial assembly, where vibration resistance and consistent clamping force are paramount. The integrated 26mm flange eliminates the need for separate washers, distributing load evenly to prevent material indentation and maintain joint integrity in automotive and construction applications. Made from zinc yellow-chromate plated steel, it combats corrosion in outdoor or chemically exposed settings, while the M12 coarse thread and external hex drive enable rapid installation with standard tools, reducing labor time. By conforming to DIN 6923 and ISO 4161, it ensures reliable performance in machinery, structural frameworks, and equipment requiring metric flange nuts with high-strength credentials.

Specification Summary & Compliance

This flange nut adheres to precise dimensional tolerances, including a Thread Fit of Class 6H for consistent engagement and a flange diameter of 26mm with 1.8mm thickness as per standard specifications. It complies with DIN 6923 and ISO 4161 manufacturing norms, ensuring metric thread accuracy and performance reliability. The product meets common industry requirements for material and safety, though specific declarations for RoHS or REACH should be verified per batch, given its steel construction and plating.
