Mit besonderem Vorteil erstreckt sich dabei die Stirnfläche des Ansatzes in einer Normalebene der Nagelachse.extremely advantageous design of the nail head in terms of production engineering and functional engineering is achieved when the upper outer surface of the nail head is in an approach with approximately the shaft diameter corresponding diameter expires. With particular advantage, the end face of the attachment extends in one Normal plane of the nail axis.

Auch beim erfindungsgemäßen Nagel können gegebenenfalls anstelle von Stahlrondellen zerstörbare Kunststoffrondellen als vordere Führungsmittel verwendet werden.In the case of the nail according to the invention, if necessary, instead of Plastic washers that can be destroyed by steel washers are used as the front guide means.

Die Erfindung soll nunmehr anhand der sie beispielsweise wiedergebenden Figur näher erläutert werden.The invention is now based on it, for example reproducing figure are explained in more detail.

Der Nagel 1 weist an den zylindrischen Schaft 2 anschließend ein konkav erweitertes Teilstück 3, einen Kopf 4 und einen darumlaufenden flachen Rand 5 auf. An der Stirnfläche des Nagelkopfes ist ein Ansatz 6 vorgesehen, dessen Durchmesser im wesentlichen dem Schaftdurchmesser entspricht. Dieser Ansatz weist im gezeichneten Fall eine Stirnfläche 7 auf, die sich in einer Normalebene der Nagelachse erstreckt.The nail 1 has on the cylindrical shaft 2 then a concave widened section 3, a head 4 and a surrounding flat edge 5. On the end face of the nail head, a projection 6 is provided, the diameter of which corresponds essentially to the shaft diameter. In the case shown, this approach has an end face 7 which extends in a normal plane of the nail axis.
