Our 8.8 Grade High-Strength Galvanized Flange Bolt is a top-tier carbon steel fastener engineered for heavy-duty industrial, mechanical, and structural applications. Manufactured to strict international standards (DIN 6921, ISO 4162, GB 16674), this bolt features an integrated hex flange head that combines the functions of a standard bolt and a flat washer, delivering exceptional load distribution, vibration resistance, and structural stability. The 8.8 strength grade (quenched and tempered carbon steel) ensures a minimum ultimate tensile strength of 800 MPa and a yield strength of 640 MPa, while the zinc-plated (galvanized) finish provides reliable corrosion resistance for indoor and outdoor environments. Designed for easy installation, reusability, and long-term durability, this flange bolt is a cost-effective, high-performance solution for engineers, contractors, and manufacturers worldwide.
