Material and finish

Made of high-quality steel and provided with an electrolytic zinc coating, this bolt offers increased corrosion resistance. The zinc layer of approximately 5 μm protects against rust formation and extends the bolt's lifespan, even in humid environments.

Standards and compatibility

This bolt complies with DIN 933 and ISO 4017 standards, ensuring consistency and compatibility with other fasteners. The precise manufacturing ensures a perfect fit in standard nuts and tapped holes with tolerance class 6H.

Areas of application

This hexagon head bolt is ideal for:

• Construction sector: Fastening steel structures and support beams.
• Mechanical engineering: Assembly of heavy machinery and equipment.
• Automotive: Fastening chassis components and other critical parts.

Advantages of electrolytic zinc coating

• Corrosion resistance: The zinc layer provides protection against rust and corrosion.
• Aesthetically pleasing: The bright finish ensures a neat appearance.
• Compatibility: Fits standard nuts and tapped holes without additional processing.

Important considerations

When using electrolytically zinc-plated bolts in high-strength applications, such as 8.8, it is important to consider possible hydrogen embrittlement. This phenomenon can occur during the plating process and affect the ductility of the steel. Ensure proper application and consider alternative coatings if necessary.
