Product Description

Hex flange screws M5x8, conforming to DIN 6921 standards, feature a 5mm diameter and 8mm nominal length with a hexagonal head and integrated washer-style flange. These M5x8 hex flange bolts are typically manufactured in steel grades 8.8 or 10.9, with optional zinc-plated or galvanized coatings for corrosion resistance. Designed for structural fastening in automotive assemblies, machinery, and industrial equipment, they operate effectively within -30°C to +120°C environments. The DIN 6921 flange screws provide enhanced load distribution through their 11.3mm flange diameter, reducing surface pressure on substrates. Advantages include vibration resistance and simplified installation with standard hex tools, though the compact 8mm length limits use in thick materials. Their 4mm hexagonal drive requires a 8mm wrench for secure torque applications.
