  1. Ein neuartiger, verbesserter Aufbau einer Holzschraube, besteht aus einem Schraubenkörper mit einem glatten Oberschnitt und einem Mittelschnitt mit Rundgewinden, gekennzeichnet dadurch, daß der Unterschnitt dieses Schraubenkörpers eine Mehrheit von spiralförmigen, viereckigen Spiralgewinden jeweils im Aufbau mit verschiedenen Winkeln aufweisen, deren besonderer Aufbau ermöglicht, daß eine Holzplatte bei der Festziehung der Schraube leichter geschnitten werden kann. Die Schraube kann somit kraftsparend, stoßunempfindlicher und ohne Rißbildungsgefahr in eine Holzplatte festgezogen werden.
