Abstract

1. Phillips screw (3) which is suitable for receiving a cap (26) and has four individual slots (5) which extend axisymmetrically from the screw head surface (11) and lie with their radially limiting flanks (9) on the lateral surface area of an inverted truncated cone and which are followed by a coaxial truncated cone-shaped recess (15), the two side walls (8) of each individual slot (5) running parallel to one another and radial impressed sections (20) being provided between each pair of peripherally adjacent individual slots (5), characterised in that the impressed sections (20) are lateral areas of cylinder segments parallel to the axis (6) of the screw (3), the cylinder axes of which, on the angle bisector between each pair of peripherally adjacent individual slots (5), are staggered outwards radially from the screw axis (6) and of which the generating line, producing each lateral limitation, is formed by a sharp edge (23) which at the same time forms an axially parallel limitation of the adjacent side wall (8) in the direction of the screw axis (6).
