Abstract
A screw with a polygonal cross section comprises a threaded section and a non-threaded section that extends from the threaded section to a front, rounded screw tip. The sideline of the non-threaded section runs smoothly and without interruption from the threaded section to the tip at a constant curvature. The screw is used to attach an element to a panel component, wherein the screw itself produces the hole in the panel component and forms the threads.
