Specification

SEODescription

The Hex Flange Screw M6x16, also known as M6 Hex Flange Bolt 16mm, is a DIN 6921 Flange Screw M6-compliant fastener designed for robust industrial applications. Featuring an integrated hexagonal flange head (13mm diameter) with serrated underside for vibration resistance, it eliminates the need for a separate washer. The M6x16 thread (6mm diameter, 16mm length) is typically crafted from grade 8.8 steel or A2-70 stainless steel, with optional zinc plating for corrosion protection. Suitable for automotive assemblies, machinery manufacturing, and electrical enclosures, it operates effectively in temperatures from -50°C to 120°C. Advantages include high shear strength (up to 640N/mm²) and simplified installation using standard 10mm hex tools, though limited accessibility in tight spaces may require specialized drivers.
