Benefits of electrolytic zinc plating

Electrolytic zinc plating provides a protective layer that shields the screw from corrosion. This extends the lifespan and ensures reliable fastening, even in humid conditions.

Packaging and availability

Important considerations

When using electrolytically zinc plated screws, it is important to consider the possibility of hydrogen embrittlement. This phenomenon can occur during the plating process and affect the strength of the screw. Ensure the screws are installed correctly and avoid excessive loads to guarantee optimal performance.
