Abstract

Ecrou limiteur de couple comportant une portion filetée et une portion non filetée séparées par une région de faible section susceptible d'être cisaillée. La surface extérieure de l'écrou est recouverte par une enveloppe isolante qui maintient la portion non filetée après cisaillage ou évite qu'elle provoque des courts-circuits après cisaillage et chute dans l'installation. Cet écrou est avantageusement utilisé pour le serrage de pièces électriques.Torque limiting nut comprising a threaded portion and an unthreaded portion separated by a region of small section capable of being sheared. The outer surface of the nut is covered by an insulating casing which maintains the unthreaded portion after shearing or prevents it causing short circuits after shearing and falling into the installation. This nut is advantageously used for tightening electrical parts.
