Abstract

Elémcnt de fixation comportant deux tiges de boulon et une bride de faible hauteur intercalée entre elles et dont elle est solidaire, cette bride comportant des protubérances sur sa face extérieure. Les saillies de la bride consistent en des nervures orientées radialement, dont chacune comporte une surface primaire 26, d'entraînement en orientation, orientée perpendiculairement à la face extérieure de la bride et dirigée vers l'extérieur, et une surface secondaire 28 qui monte de la face extérieure de la bride en direction de la surface primaire pour venir au contact d'un outil de forme complémentaire, servant à faire tourner l'élément de fixation autour de son axe géométrique pour l'enfoncer dans l'alésage de la pièce à fixer. Application aux éléments de fixation s'encastrant dans des pièces de matière plastique.
