ISO 7380-1 10.9 zinc-nickel black Bolt with semi-round head and internal hexagon

Overview

The ISO 7380-1 bolt with a semi-round head and internal hexagon is the ideal choice for applications where aesthetics and functionality are important. This fastener ensures a secure connection thanks to its design, which allows for precise tightening without the risk of damage. The semi-round head shape facilitates convenient installation in confined spaces while maintaining the product’s aesthetic appearance. The bolts are made of carbon steel and feature a black zinc-nickel coating, which provides additional corrosion protection.

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

The key advantages of the zinc-nickel coating are:

• Excellent corrosion resistance—more than three times higher than that of regular 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 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 low visibility—the coating has a deep black color, making it virtually invisible.
