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 () extending along a central longitudinal axis (A) and a subsequent tip region (). The shaft section () includes, as viewed from the head, a threadless underhead section (), a stop collar () and a threaded section (). The thread in a first part () of the threaded section () subsequent to the stop collar () has an outer diameter D, which is attenuated compared to the thread in a second part () with outer diameter D, over several convolutions, so that D<D. This threaded sectionallows 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.
