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.The head (3) of the screw (1) has an engagement surface (5) with a tightening key, having a multi-lobed profile (7) in a plane perpendicular to the axis of the screw and which comprises a series of liangularly distributed on the circumference and projecting radially outward, each of said lobes comprising two radial surfaces (8) which lie at least partially in two planes passing through the axis (9) of the screw and a central section ( 10) which joins the outer radial ends of the two faces (8) of each lobe. The portions (13) of the surface for engagement with the tightening key which define said central sections of the lobes of the multi-lobed profile are located on a single imaginary surface, conical or pyramidal, coaxial with the screw.
