Screw having a screw head, a screw shaft, and a conical, wavy flange

The invention relates to a screw having a screw head (2), a screw shank (1) and a corrugated conical flange (4) which decreases in thickness toward the outside, which flange (4) will abut on a component part as the screw is being screwed into the latter. The two lateral surfaces (5, 6) of the flange...

Beschreibung
Zusammenfassung:	The invention relates to a screw having a screw head (2), a screw shank (1) and a corrugated conical flange (4) which decreases in thickness toward the outside, which flange (4) will abut on a component part as the screw is being screwed into the latter. The two lateral surfaces (5, 6) of the flange (4) from the screw shank (1) to the outer edge (7) of the flange taper continuously toward the outside with the thickness of the flange (4) decreasing at the same time, with its corrugation (8) extending substantially over the entire radial width of the flange (4).
