Alusistemi self-tapping screw for fixings on wood.
The screw is designed for the installation of PV systems on wooden roofs, offering a secure and durable fastening system. The double thread ensures efficient penetration and superior hold in wood, making it ideal for structural mountings of profiles and load-bearing stringers.
Tightness and protection even in outdoor environments
Made entirely of A2 stainless steel, this screw resists wear, corrosion and weathering. The EPDM gasket prevents water seepage at the point of attachment, protecting both roof and supporting structure over time.
Adjustable and precise installation
