Zusammenfassung:The present invention relates to a clamping screw (6) for osteosynthesis, comprising at least one screw thread (7, 10) along a main axis (X) and, at its end referred to as the apex end (11), having a socket (12) which, about said main axis (A), has evenly angularly distributed shapes designed to accept complementing shapes of a screwdriver (19) engaged in said socket (12), notable in that the socket (12) of the screw (6) comprises at least three regular shapes (13) of which the vertices are inscribed inside a circle referred to as circumscribed circle (30) and at least two adjacent vertices of the socket (21) are connected to form a convex lobe referred to as indexing lobe (16) of which the radius of curvature is equal to the radius of the circumscribed circle (30).
