A facade panel screw for the optimized fastening of facade panel elements on a substructure has a head with very large diameter D, a substantially cylinder cross-sectional shaft, which is at least partially provided with a thread (nominal diameter D) and a conical tip comprising a tip angle &#x3b3;. The thread extends continuously from the shaft to the tip. It is characterizing that the tip angle &#x3b3; is 45&#xb0;+/&#x2212;10&#xb0;, the thread is embodied at least in a two-threaded manner, the head diameter Dis embodied at least twice as large as the nominal diameter D; and the facade panel screw does not have a drill tip. Such a facade panel screw is used in a fastening arrangement, which comprises a load-bearing component (substructure) and a facade panel. Due to its design, the facade panel screw is able to simplify the fastening of the facade panel and to at least partially correct an inclined positioning in response to the installation.

Facade panel screw and fastening arrangement comprising same

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&#x3c;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.
