In order to provide a combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, and also a sleeve which incorporates a narrowed section the internal diameter of which is smaller than the external diameter of the threaded portion, whereby said combination is producible in a simple manner but nevertheless ensures that the sleeve is held securely on the screw member, it is proposed that the sleeve be in multipart form at least in the narrowed section thereof, that the shank portion of the screw member be passed through the narrowed section of the sleeve and that the several parts of the sleeve be connected to one another in such a manner that the sleeve is held captive on the screw member.
