12.9 Grade โ White zinc โ Hexagon bolt
Grade 12.9 hexagon bolts represent the pinnacle of strength in standard metric fastening. Manufactured from premium alloy steel, these bolts are quenched and tempered to achieve an impressive minimum tensile strength of 1200 N/mmยฒ. They are the ultimate choice for critical applications where maximum clamping force is required within a compact space. The white zinc plating provides a clean finish and temporary corrosion protection, allowing these high-performance components to be used in precision machinery and heavy engineering.
- Maximum Strength: The highest strength class available for standard fasteners (1200 MPa), offering unparalleled load-bearing capacity.
- Alloy Construction: Made from superior alloy steel to ensure exceptional hardness and resistance to fatigue.
- Precision Use: Designed for applications requiring immense clamping loads, such as hydraulic presses and injection molding machinery.
