Metric Class 8.8 Hex Flange Bolt, Non Serrated, DIN 6921, Zinc CR+3
Our Metric Class 8.8 Hex Flange Bolts manufactured to DIN 6921 with a non‑serrated flange and Zinc CR+3 finish are designed for reliable, high‑strength fastening in industrial, mechanical, and general‑purpose applications. Produced from medium‑carbon steel and heat‑treated to Class 8.8 specifications, these bolts provide a balanced combination of tensile strength, toughness, and durability suitable for structural and load‑bearing assemblies.
The non‑serrated flange acts as an integrated washer, evenly distributing clamp load without damaging the mating surface. This makes these bolts ideal for applications requiring surface protection, controlled torque characteristics, or reusability. The Zinc CR+3 (trivalent chromium) plating enhances corrosion resistance while providing a clean, bright finish, making these fasteners suitable for indoor and light‑to‑moderate outdoor environments.
