Product Details
Our Black DIN 934 Hex Nuts are manufactured to deliver reliability, strength, and a superior finish for a wide range of fastening needs.
- DIN 934 Standard for Universal Compatibility: These nuts are manufactured in strict accordance with DIN 934, the German standard for finished hex nuts. This ensures consistent dimensions, thread tolerances, and mechanical properties, guaranteeing a perfect fit with any standard metric bolt, stud, or threaded rod. The standard specifies two product grades:
- Grade A: For nominal thread diameters up to M16.
- Grade B: For nominal thread diameters greater than M16.
- High-Strength Carbon Steel Construction: Forged from high-quality carbon steel, these nuts are available in various mechanical property classes (e.g., Class 4, 6, 8, 10), providing reliable strength and proof load capacity for creating secure and durable bolted joints.
- Dual Finish Options for Performance and Aesthetics:
- Black Zinc Plating: This finish involves electroplating a layer of zinc onto the carbon steel, followed by a black chromate conversion coating. It offers good corrosion resistance, making it suitable for outdoor and general industrial use, along with a decorative, semi-gloss black appearance.
- Black Oxide Coating: This is a conversion coating that provides mild corrosion resistance and a deep, matte black finish. It is an ideal choice when a non-reflective appearance is desired and does not add significant thickness to the part, preserving tight thread tolerances.
