Specification

SEODescription

The M5 flange head screw, conforming to DIN 6921 hex bolt standards, is a 35mm hex flange bolt designed for robust mechanical fastening in industrial applications. With a 5mm thread diameter and 35mm shank length, it integrates a hexagonal head and built-in flange washer for secure, vibration-resistant assembly. Typically crafted from grade 8.8 steel or stainless steel (A2/A4), it operates in temperatures ranging from -50°C to 150°C, suitable for automotive, machinery, and structural systems. The flange design eliminates separate washers, providing uniform load distribution and self-alignment. While offering high shear resistance and corrosion protection (zinc-plated or galvanized), its hexagonal profile requires adequate installation clearance. Commonly used in engine components, electrical enclosures, and heavy-duty equipment, this fastener combines durability with simplified assembly, though precise torque control is critical to avoid flange deformation.
