DIN 7990 hexagon bolts are high-tensile structural fasteners designed for heavy-duty applications such as steel construction and industrial frameworks. Manufactured to strict DIN standards, these bolts provide superior strength, durability, and resistance to extreme loads.
Introduction
DIN 7990 hexagon bolts are widely used in structural steel connections, bridge construction, and heavy machinery due to their exceptional strength and durability. These bolts feature a hexagon head design, allowing easy installation with wrenches or sockets. Their large width across flats ensures better grip and stability, making them a preferred choice for high-load applications.
Key Features
- Hexagon Head: Provides a secure grip for torque application.
- High Tensile Strength: Withstands heavy loads and extreme pressure.
- Large Width Across Flats: Ensures improved stability in structural joints.
- Threaded Shank: Allows compatibility with various nuts and fittings.
- Corrosion Resistance: Available in zinc-plated, hot-dip galvanized, and black oxide coatings for enhanced durability.
Material and Classification
DIN 7990 bolts are manufactured from high-strength carbon steel, ensuring excellent mechanical properties. These bolts are available in various coatings for added protection against corrosion.
| Material Type | Strength Class | Coating Options |
|---|---|---|
| Carbon Steel | 8.8, 10.9 | Zinc-Plated, Galvanized, Black Oxide |
| Stainless Steel | A2, A4 | Polished, Passivated |
| Alloy Steel | 10.9, 12.9 | Heat-Treated, Phosphated |
