ISO 7380-2 10.9 zinc-nickel black Bolt with semi-round head and internal hexagon

Overview

The ISO 7380-2 round head bolt with internal hexagon and strength class 10.9, finished with a black zinc-nickel coating, is an ideal choice for a variety of industrial applications. The increased strength ensures reliable connections even under heavy loads, and the zinc-nickel coating protects against corrosion, extending the service life of the product. The semicircular shape of the head not only provides an aesthetic appearance, but also helps reduce the risk of damage to surrounding surfaces. Thanks to the internal hexagon, installation remains fast and convenient, even in cases of limited space. This bolt is widely used in mechanical engineering, the automotive industry, as well as in the manufacture of furniture and electronics.

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

The key advantages of zinc-nickel coating 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 in combination with aluminum parts;
• Increased heat resistance - retains its protective properties during temperature fluctuations and during prolonged operation in high-temperature conditions;
• Mechanical strength - harder than pure zinc, has better resistance to scratches and wear;
• Environmental friendliness - less oxidation products are formed, resulting in lower zinc emissions into the environment throughout the product's life cycle.
• Aesthetics and inconspicuousness - the coating has a deep black color, which makes it inconspicuous.

Areas of application

ISO 7380-2 round head bolts with hexagon socket, grade 10.9, zinc-nickel plated in black, are ideal for applications where high reliability and corrosion resistance are required. These bolts are used in various industries, including mechanical engineering, automotive and construction, where mechanical properties and durability of the connections are important.

The round head shape provides an aesthetic appearance and reduces the risk of damage to other components, while the hexagon socket allows for convenient tightening of the bolts in confined spaces. Made of high-quality carbon steel, these bolts have increased wear resistance thanks to a special coating that provides additional protection against aggressive environments.
