Abstract

Ecrou d’un système de fixation comportant un tronçon conique L'invention a pour objet un écrou d’un système de fixation qui comprend un système d’accouplement à un outil rotatif, au niveau d’une de ses extrémités, et au moins un premier tronçon (50) conique offrant une surface latérale tronconique. Ce tronçon (50) conique rend difficile voire impossible l’utilisation d’un outil, comme une pince multiprise, pour faire pivoter l’écrou et limite les risques d’impact sur des pièces avoisinantes. L’invention a également pour objet une grille de perçage comportant au moins un système de fixation comportant un tel écrou. Figure 3
