Nut DIN 934 M4 6 zinc-nickel black

A hexagonal nut is a fastener with a thread that forms a connection with a screw, bolt, or stud. Thanks to its shape, it ensures an even distribution of the load on the surfaces of the connected parts.

Application: construction, mechanical engineering, automotive industry, electrical engineering.

Material of manufacture: high-strength structural alloy steel, strength class 6.

Coating: Zinc-nickel black. Zinc-nickel coating is an innovative anti-corrosion solution for fasteners that combines high protective ability, mechanical strength and environmental safety.

The key advantages of zinc-nickel coating are:

• Excellent corrosion resistance - more than three times higher than that of ordinary zinc;
• Low risk of hydrogen embrittlement;
• Compatibility with aluminum - does not form galvanic couples and does not cause corrosion in combination with aluminum parts;
• Increased heat resistance - retains its protective properties at changing temperatures and during prolonged operation in high-temperature conditions;
• Mechanical strength - harder than pure zinc, has better resistance to scratches and wear;
• Environmental friendliness - less formation of oxidation products, which means lower zinc emissions into the environment throughout the product's life cycle.
• Aesthetics and invisibility - the coating has a deep black color, which makes it hardly noticeable.
