For the direct attachment of terrace boards to aluminum system profiles and aluminum functional strips with a recessed web.

Product info: Specifically designed for securing terrace boards to aluminum substructure profiles, rust-resistant, not acid-resistant. 10 years of experience without corrosion issues with suitable woods. Not suitable for highly tannin-rich woods such as Cumaru, oak, Merbau, Robinia, etc. Drilling capacity: 3 mm in aluminum, not suitable for chlorine-containing atmospheres. Non-corrosive steel according to DIN 10088.

Application notes: The drill tip ensures that the screw independently forms a drill hole and a counter-thread in the aluminum substructure. The terrace board should always be pre-drilled to Ø 5.5 mm. The screw's drilling capacity is designed for profile wall thicknesses of up to 3.5 mm. To ensure sufficient grip of the screw in the aluminum, the wall thickness of the aluminum profiles should not be less than 2.2 mm.

Note: This screw is specifically developed for the attachment of terrace boards to aluminum substructure profiles with a recessed web. When fastening to conventional hollow sections, spacers (at least 5 mm) must be used, as the screw needs space to move.
