Abstract

The lag bolt comprises a machine thread, which is formed on the shank between a hexagon head and a wooden thread. The diameter of the machine thread is larger than the diameter of the wooden thread. A screw nut is guided problem-free through the wooden thread fitted to the machine thread.

Description

Diese Schlüsselschraube ist mit einem Maschinengewinde auf dem Schaft versehen, welches sich zwischen Sechskantkopf und Holzgewinde befindet. Bei herkömmlichen Ausführungen ist dieser Abschnitt der Schraube unbearbeitet und blank.This key screw is provided with a machine thread on the shaft, which is located between hexagon head and wood thread. In conventional designs, this section of the screw is unworked and bright.

Das erwähnte Maschinengewinde misst in seinem Durchmesser immer etwa 2 mm mehr, als der des Holzgewindes. Somit wird ermöglicht, dass eine passende Mutter ohne Probleme zum Maschinengewinde hingeführt und auf dieses aufgeschraubt werden kann, wodurch sich vielseitigere Anwendungsmöglichkeiten im Vergleich zur herkömmlichen Ausführung ergeben.The mentioned machine thread measures in its diameter always about 2 mm more than that of the wood thread. Thus, it is possible that a suitable nut can be brought without problems to the machine thread and screwed onto this, resulting in more versatile applications compared to the conventional design.

Schraubt man beispielsweise eine solche Schlüsselschraube durch eine Holzplatte, die dünner ist als die zur Verfügung stehende Länge des Holzgewindes, kann man mit einer passenden Unterlegscheibe und Mutter beide Teile fest miteinander verbinden, die Schraube ist sicherer am Werkstück befestigt und bricht zum Beispiel wesentlich seltener aus.For example, screwing such a key screw through a wooden plate that is thinner than the available length of the wood thread, you can connect both parts firmly with a matching washer and nut, the screw is securely attached to the workpiece and breaks, for example, much less ,
