DIN 912 8.8 zinc-nickel black Bolt with cylindrical head and internal hexagon

Overview

The DIN 912 8.8 zinc-nickel black bolt is a high-quality fastener with a cylindrical head and internal hexagon, which provides a reliable connection even in the most difficult conditions. This bolt is ideal for applications where high connection strength is important and access for tools is limited. The strength class 8.8 guarantees resistance to significant loads, and the zinc-nickel coating provides additional corrosion protection, increasing the durability of the product. This bolt is an excellent choice for industry, automotive, and the energy sector, where both functionality and aesthetics are important.

Coating: Zinc-nickel coating is an innovative anti-corrosion solution for fasteners, combining high protection, 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 vapors and does not cause corrosion in combination with aluminum parts;
- Increased heat resistance - retains protective properties during temperature changes 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, respectively 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 inconspicuous.

Areas of application

The DIN 912 hexagon socket head cap screw is an indispensable element in many industries, including mechanical engineering, automotive, energy and construction. This type of bolt is ideal for connecting components in tight spaces where the use of a traditional wrench is difficult or impossible.

Thanks to the hexagon socket, the bolt allows for efficient and reliable tightening, withstanding significant torques. The strength class 8.8 ensures high reliability, and the zinc-nickel coating in black not only increases corrosion resistance, but also provides an aesthetic appearance, making it ideal for visible connections. This bolt will be a reliable choice for any project that requires high quality and durability.
