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.

Facade panel screw and fastening arrangement therewith

A method for establishing a connection, with the following steps: inserting a sleeve () having a stop flange () into a bore (), in such a way that the stop flange () is at a distance from a bore edge (); anchoring at least one elevation () of a free end portion () of the sleeve () in the bore wall () by widening the free end portion () of the sleeve (); and moving the stop flange () in the direction of the at least one fixed anchored elevation () of the free end portion () of the sleeve (), by widening a further portion () of the sleeve.
