Professional Applications & Engineering Value

This M16 flange nut is engineered to address critical challenges in industrial fastening, where vibration resistance, corrosion protection, and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides a durable barrier against oxidation and chemical exposure, making it ideal for outdoor machinery, automotive assemblies, and construction equipment. The integrated flange acts as a built-in washer, distributing clamping force over a wider area (34.5mm diameter) to prevent surface indentation and maintain joint stability. With its fine metric thread and Class 10 strength, it effectively resists loosening in high-stress environments, reducing maintenance downtime and ensuring long-term operational safety. This nut is a trusted solution for engineers seeking reliable performance in demanding heavy-duty applications.

Specification Summary & Compliance

This flange nut features a Class 6H thread fit for precise engagement and consistent torque application.
