Die Sperrverzahnung an der Auflagefläche verkrallt sich mit dem Gegenstück und verhindert, dass sich die Schraubverbindung durch Vibrationen oder Temperaturwechsel selbstständig löst.\"}},{\"@type\":\"Question\",\"name\":\"Wofür wird die Sperrzahnmutter verwendet?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Sie dient als Verbindungselement innerhalb der Novotegra Montagesysteme, etwa zur Befestigung von Modulklemmen, Profilverbindern und Endkappen. Durch die Sperrverzahnung bleibt die Verbindung auch bei wechselnder Belastung dauerhaft fest.\"}},{\"@type\":\"Question\",\"name\":\"Warum ist eine Sperrverzahnung wichtig?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Auf dem Dach wirken über Jahre Wind-, Schnee- und Temperaturlasten auf die Verschraubungen. Die Sperrverzahnung sichert die Mutter formschlüssig gegen selbstständiges Lösen und erhält so die Klemmkraft der gesamten Modulbefestigung ohne zusätzliche Sicherungselemente.\"}},{\"@type\":\"Question\",\"name\":\"Ist die Mutter für den Außeneinsatz geeignet?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Ja. Die Ausführung aus Edelstahl V2A ist rostfrei und witterungsbeständig, wodurch sie Regen, Frost und UV-Strahlung über die gesamte Lebensdauer einer Photovoltaikanlage standhält.\"}},{\"@type\":\"Question\",\"name\":\"Wer ist Novotegra?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Novotegra ist ein etablierter Hersteller von Montagesystemen für Photovoltaikanlagen und liefert aufeinander abgestimmte Komponenten für Schräg- und Flachdächer.
