TORX screw made of low-carbon steel with an EPDM washer, for fixing sheets to wooden substrate, dedicated to modular metal roof tiles (MODULAR SERIES) and compact metal roof tiles (COMPACT SERIES). The screw is also designed for stitching sheets together on vertical embossments. The main advantage is the ergonomic shape of the head thanks to which they are less visible, which gives an aesthetic appearance to the entire roof. The screws are available in colours compatible with the roof covering.
