Product Details
Our Hot-Dip Galvanized DIN 934 Hex Nuts are manufactured with a focus on durability, reliability, and precision.
- Superior Hot-Dip Galvanized (HDG) Coating: This is the gold standard for corrosion protection. The process involves immersing the carbon steel nuts in a bath of molten zinc at high temperatures. This creates a thick, durable, and metallurgically bonded alloy coating that is far superior to standard electro-zinc plating. The HDG finish provides both barrier and sacrificial protection, meaning the zinc coating will corrode preferentially to protect the steel nut, even if scratched.
- DIN 934 Standard for Universal Compatibility: Manufactured in strict accordance with DIN 934, these nuts feature standardized dimensions, thread profiles, and mechanical properties. This guarantees a perfect and reliable fit with any standard metric HDG bolt, stud, or threaded rod, simplifying assembly and ensuring consistent clamping force.
- High-Strength Carbon Steel Construction: The nuts are made from quality carbon steel, available in various strength classes (e.g., Class 6, 8, 10). This provides the necessary proof load and tensile strength to create secure, heavy-duty bolted joints capable of withstanding significant stress.
- Overtapped Threads for Proper Fit: To accommodate the significant thickness of the hot-dip galvanized coating, these nuts are manufactured with threads that are tapped oversize. This is a critical manufacturing step that ensures a smooth, proper fit when used with a standard hot-dip galvanized bolt, preventing thread binding (galling) and ensuring the joint can be properly tensioned.
