Abstract

La présente invention a pour objet un écrou autobloquant ayant structure d'un écrou à profil externe polygonal et avec un trou central muni d'un filetage interne, l'autoblocage de cet écrou étant obtenu sur une vis ayant un filetage externe correspondant à celui de l'écrou et ayant donc le même pas. Cet écrou comprend une cage comportant un profil externe polygonal, une embouchure et un fond de support, et des éléments annulaires formant le filet, et est caractérisé en ce qu'il comporte à l'intérieur de la cage au moins deux éléments présentant chacun un trou interne muni d'une portion de filetage égale à au moins 1,2 pas dudit filetage, cette portion de filetage étant obtenue par enlèvement de matière. La présente invention se rapporte à un écrou autobloquant et procédé pour sa fabrication.
