DIN 934 6 zinc-nickel black Hexagonal nut

Overview

DIN 934 is a hex nut with a full internal metric thread, made of steel with a black zinc-nickel coating. This coating provides high corrosion resistance, making the nut suitable for use in aggressive environments. The nut has strength class 6, ensuring reliable connections under load.

It is available in various sizes, allowing the most suitable option to be selected for specific requirements. The black coating not only improves the appearance but also enhances corrosion protection. Thanks to its properties, the DIN 934 hex nut with a black zinc-nickel coating is an excellent choice for industrial and construction applications.

Coating: black zinc-nickel.

Zinc-nickel coating is an advanced anti-corrosion solution for fasteners that combines high protective performance, mechanical strength, and environmental benefits.

Key advantages of zinc-nickel coating:

• Excellent corrosion resistance — more than three times higher than conventional zinc coating;
• Low risk of hydrogen embrittlement;
• Compatibility with aluminum — it does not form galvanic couples or cause corrosion when used in combination with aluminum components;
• Improved heat resistance — retains its protective properties during temperature fluctuations and prolonged operation under high-temperature conditions;
• Mechanical strength — harder than pure zinc and offers better resistance to scratches and wear;
• Environmental benefits — reduced formation of oxidation products results in lower zinc emissions into the environment throughout the entire product life cycle;
• Aesthetic appearance and low visibility — the coating has a deep black color, making the fastener less noticeable.

Applications

The DIN 934 strength class 6 hex nut with a black zinc-nickel coating is ideal for applications requiring increased corrosion resistance. Thanks to its zinc-nickel coating, it provides reliable protection against aggressive environments, making it suitable for mechanical engineering, construction, and steel structure assembly.

This hex nut has standard dimensions, allowing it to be easily integrated into various fastening systems.
