Abstract

La tete (3) de la vis (1) présente une surface (5) d'engagement avec une clé de serrage, ayant un profil polylobé (7) dans un plan perpendiculaire à l'axe de la vis et qui comprend une série de lobes équiangulairement répartis sur la circonférence et faisant radialement saillie vers l'extérieur, chacun desdits lobes comprenant deux surfaces radiales (8) qui se situent au moins partiellement dans deux plans passant par l'axe (9) de la vis et une section centrale (10) qui réunit les extrémités radials extérieures des deux faces (8) de chaque lobe. Les portions (13) de la surface d'engagement avec la clé de serrage qui définissent lesdites sections centrales des lobes du profil polylobé sont situées sur une surface imaginaire unique, conique ou pyramidale, coaxiale avec la vis.
