Patent ID: 11187260

Abstract:
A facade panel screw for the optimized fastening of facade panel elements to a substructure has a head having a very large diameter, a subsequent, essentially cylindrical shaft section (22) extending along a central longitudinal axis (A) and a subsequent tip region (23). The shaft section (22) includes, as viewed from the head, a threadless underhead section (24), a stop collar (25) and a threaded section (28). The thread in a first part (26) of the threaded section (28) subsequent to the stop collar (25) has an outer diameter Dr, which is attenuated compared to the thread in a second part (27) with outer diameter Dn, over several convolutions, so that Dr<Dn. This threaded section 26 allows a controlled overwinding of the facade panel screw in use. A corresponding fastening arrangement includes a facade panel, a substructure for transferring the load to a building surface and the facade panel screw.
