Additional significant anti-corrosion protection and a perfect match to the covering color in the RAL/NCS palette.

2. EPDM washer

Made of the best sealing material - EPDM. It does not lose its elasticity over time and has a very long aging period. Resistant to changing weather conditions and UV radiation. After installation, it self-vulcanizes to the sheet metal, creating a tight connection.

3. Hexagonal head with marking

The hexagonal head ensures easy and secure screw installation, which significantly simplifies work and increases installation efficiency. The distinctive marking of ETANCO products allows for easy identification; each production batch receives a unique number, allowing for precise identification.

4. Thread under the screw head

The additional thread with an increased diameter ensures proper distribution of the EPDM washer on the thin cladding sheets of the sandwich panel.

5. GREY.COAT ceramic coating

Provides the highest protection against corrosion while maintaining excellent drilling ability. This allows them to be used in demanding conditions, such as a C4 class corrosive environment.

6. Self-tapping tip (double thread)

Specially designed drilling point combined with Hi-Lo thread enables direct installation in wood and concrete (in the case of concrete, a 5 mm diameter hole must first be made).

In combination with the ULTRA expansion sleeve, installation is possible in materials such as solid brick, ceramic brick, perforated brick, aerated concrete.
