8.8 Grade – White zinc – Hexagon bolt
Grade 8.8 hexagon bolts act as the universal standard for structural engineering and heavy-duty mechanical assembly. Manufactured from medium carbon steel that has been quenched and tempered, these fasteners offer significantly higher tensile strength compared to mild steel alternatives. The white zinc plating provides a dual benefit: a clean, bright aesthetic for visible machinery and a sacrificial barrier against corrosion during storage and service.
- High Strength: Heat-treated to achieve a minimum tensile strength of 800 N/mm², making them suitable for critical load-bearing joints.
- Standard Finish: Electro-galvanized with white zinc (clear chromate) to resist oxidation in indoor or protected environments.
- Versatile Supply: Whether you need a small batch for vehicle repair or bulk pallet quantities for construction, we accommodate all order sizes.
