| description | A system for driving a screw, comprising a screw and a corresponding tool, the screw head having a hexalobular slot (2) in the upper surface of the screw head, an upper peripheral wall (9) of hexalobular planform extending down into the screw head, the upper peripheral wall (9) being parallel or near parallel to the axis of the screw, a sloping transition surface (15) extending downwardly and inwardly with respect to the lower edge of the upper peripheral wall (9), and a tapered recess (11) extending downwardly from the lower edge of the sloping transition surface (15), in which the dimensions of the screw head are such that when the screw head is engaged by a tool (6) having upper (16) and lower (17) engagement sections, and in which the upper engagement section (16) is tapered downwardly at an angle with respect to the axis of the screw to which the tool is to engage and the lower engagement section (17) is tapered downwardly, so that there is a 'stick fit' between the surface of the tapered recess (11) and the external surface of the lower tapered engagement section (17), and there is no engagement with the sloping transition surface (15).
L'invention concerne un système permettant de visser une vis, comportant une vis et un outil correspondant, la tête de vis ayant une fente hexalobulaire (2) au niveau de la surface supérieure de la tête de vis, une paroi périphérique supérieure (9) de forme plane hexalobulaire s'étendant vers le bas dans la tête de vis, la paroi périphérique supérieure (9) étant parallèle ou presque parallèle à l'axe de la vis, une surface de transition inclinée (15) s'étendant vers le bas et vers l'intérieur par rapport au bord inférieur de la paroi périphérique supérieure (9), et un évidement conique (11) s'étendant vers le bas en provenance du bord inférieur de la surface de transition inclinée (15), les dimensions de la tête de vis étant telles que, quand la tête de vis est enclenchée par un outil (6) ayant une section d'enclenchement supérieure (16) et une section d'enclenchement inférieure (17), et la section d'enclenchement supérieure (16) étant conique vers le bas selon un angle par rapport à l'axe de la vis avec laquelle l'outil doit s'enclencher et la section d'enclenchement inférieure (17) étant conique vers le bas, il y a un 'ajustement résistant' entre la surface de l'évidement conique (11) et la surface externe de la section d'enclenchement conique inférieure (17), et il n'y a pas d'enclenchement avec la surface de trans |
