The invention relates to a bone screw (1) with a screw shank (2) that can be fastened in a bone, particularly a vertebra, and a screw head (3), on which a fastening device (20) can be fastened that can be. swiveled as regards its inclination relative to the screw shank (2) and/or rotated and that displays a receptacle (26) for mounting a connecting rod. To permit swiveling of the fastening device relative to the screw shank over the largest possible angular range, as well as easy and reliable handling, the screw head (3) displays a recess (5), to which a swiveling element (6) that can be located in the recess and at least swiveled and fixed in position relative to the screw shank can be assigned, to which a fastening device (20) can be fastened. The recess (5) can be located on the screw head (3) at the level of the screw shank (2) and designed as a slot that can extend parallel to the longitudinal axis of the screw shank (2).
