Nord-Lock a créé la technologie originale de l’effet de cames qui sécurise les assemblages boulonnés, même lorsqu’ils sont exposés à des vibrations et à des charges dynamiques élevées. Le système ne peut se desserer involontairement en raison de l’effet de came créé sous la tête de vis ou sous l’écrou.
