NF E25-511 Standardmäßig Abmessungen für Conical knurled spring washers - CONTACT
'Contact' Scheiben
Die 'Contact' Scheiben werden nach der französischen Norm NFE 25-511 hergestellt. Es handelt sich um Sicherheits-Sperrkantscheiben mit einer gerändelten Oberfläche und verschiedenen Abmessungen, die an vielfältige Anwendungen angepasst werden zu können. Die konische Form übt eine 360° Schließkraft rund um die Unterseite des Schraubenkopfes oder der Mutter. Die gerändelte Oberseite verstärkt die Schließkraft weiter und hält die Befestigung unter Druck, im Falle von Vibrationen oder anderen Lockerungsfaktoren.
