250 mm
A screw length of 250 mm is designed for heavy-duty structural applications in solar, roofing, and timber construction. Its extended length allows deep anchoring in wood, steel, or aluminium profiles, ensuring exceptional load capacity and long-term stability.
250 mm screws are used in roof substructures, PV mounting systems, and load-bearing connections. Made from stainless or galvanized steel, they offer corrosion resistance, weather durability, and strong performance in outdoor solar installations.
