The Roofing screw is standard equipped with a vulcanized washer of 14 mm, EPDM galvanized, which ensures a watertight seal. The drill point of this screw is type 2 (reduced) where the drill point is narrower than the succeeding thread (thread diameter).
The maximum drilling capacity is 1 + 1 mm. Roofing screws are mainly used for facade panels that offer little mounting space or where a cover cap is not aesthetically pleasing.
Use standard cordless screwdrivers – not with impact screwdrivers.
Number of screws per board and corresponding edge distances: see board manufacturer’s instructions
The Roofing screw can be cleaned with water or a mild soap solution and a soft sponge in case of dirt caused by environmental or climatic influences (e.g. saw dust during the construction of the façade, soot deposits, flash rust in coastal areas, etc.).
If using a soap solution after cleaning, rinse the facade with water.
The use of solvents or solvents for cleaning is not permitted.
