Wholesale Stainless Flange Bolts - Trusted Exporter & Supplier
Aozhan's flange bolts integrate a built-in washer flange that distributes clamping pressure over wider surface areas to prevent loosening. Made from high-strength alloy steel (Grade 8.8-10.9) with quenching/tempering treatment, they offer superior tensile and shear resistance. Special Dacromet or hot-dip galvanized coatings provide excellent corrosion protection. Compliant with DIN 6921 standards, these bolts are essential for vibration-resistant applications like pipe flanges, wind turbines, and heavy machinery.
