Abstract

La divulgation concerne un élément de fixation à formation de filetage et à blocage de filetage combinés. L'élément de fixation comprend trois zones de filetage. Une première zone de filetage utilise un premier profil de filetage formant un filetage et présentant un diamètre externe croissant. Une seconde zone de filetage s'étend à partir de l'extrémité de la première zone utilisant le premier profil de filetage formant le filetage, et continue à diamètre constant. La troisième zone de filetage utilise un profil de filetage à blocage de filetage continuant sensiblement le long du reste de l'arbre d'un élément de fixation.
