Bolt DIN 933 M10x30 10,9 zinc-nickel black

Overview

The DIN 933 10.9 zinc-nickel black hex head bolt with full thread is a reliable fastener featuring a hexagonal head and a full thread that extends the entire length of the shank. It is typically made of carbon steel coated with a layer of zinc to protect against corrosion. The strength class of 10.9 indicates a high capacity to withstand significant loads, making it ideal for use in various applications where stability and durability are required. This bolt is suitable for structures requiring a strong connection and secure fastening.

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

The key advantages of zinc-nickel plating are:

• Excellent corrosion resistance - more than three times higher than that of conventional zinc;
• Low risk of hydrogen embrittlement;
• Compatibility with aluminum - does not form galvanic couples and does not cause corrosion when combined with aluminum parts;
• Enhanced heat resistance - retains its protective properties under temperature fluctuations and during prolonged operation in high-temperature conditions;
• Mechanical strength - harder than pure zinc, with better resistance to scratches and wear;
• Environmental friendliness - less formation of oxidation products, resulting in lower zinc emissions into the environment throughout the product’s entire life cycle.
• Aesthetics and discreet appearance - the coating has a deep black color, making it virtually invisible.
