Product Description

The Hex flange screw M5x16, compliant with DIN 6921 standards, is a metric hexagonal flange bolt designed for robust mechanical fastening. Featuring an M5x16mm thread, a built-in flange diameter of 10mm, and a hexagonal head, it eliminates the need for separate washers. This M5 flange bolt 16mm supports direct integration into machinery, automotive assemblies, or industrial equipment, offering high vibration resistance and simplified installation. Typically constructed from stainless steel or zinc-plated carbon steel, it operates in temperatures ranging from -50°C to +120°C, with corrosion-resistant coatings for harsh environments. Ideal for electronics, automotive, and heavy machinery sectors, its key advantages include space efficiency and torque stability, though access limitations in tight spaces may pose installation challenges. The DIN 6921 flange screw adheres to standardized dimensions for compatibility across modular systems.
