The furniture fitting further includes at least one drive element separate from the screw, and the drive element is movement-coupled to the screw and has a tool receiving device. The at least one screw is configured to be driven by rotating the tool receiving device with the aid of a tool. ## Claims ### Claim 1 A furniture fitting comprising a rotatably mounted screw for fixing the furniture fitting to a furniture part, wherein the furniture fitting includes a drive element separate from the screw, the drive element being movement-coupled to the screw and having a tool receiving device, wherein the screw is configured to be driven by rotating the tool receiving device with the aid of a tool, wherein the furniture fitting includes a housing having a first housing wall and a second housing wall spaced from the first housing wall, wherein a bearing portion for receiving the screw and the drive element is arranged between the first housing wall and the second housing wall, wherein the bearing portion includes a first guide for supporting the screw and a second guide for supporting the drive element, wherein the screw and the drive element are pre-fixed by a holding device in a predetermined position relative to the first and second guides of the bearing portion, and wherein the holding device is configured to be released by applying a force to the drive element with the aid of the tool, and the screw, after the holding device has been released, is displaceably supported, together with the drive element, relative to the first and second guides of the bearing portion in a direction extending transversely to the first and second housing walls. ### Claim 2 (depends on 1) The furniture fitting according to claim 1, wherein the drive element is rotatably mounted about a first rotational axis and the screw is mounted about a second rotational axis, wherein the first rotational axis and the second rotational axis are arranged so as to be laterally offset from one another. ### Claim 3 (depends on 1) The furniture fitting according to claim 1, wherein the drive element and the screw are movement-coupled to one another by cooperating tooth arrangements. ### Claim 4 (depends on 3) The furniture fitting according to claim 3, wherein one of the cooperating tooth arrangements is formed or arranged on a peripheral surface of the drive element. ### Claim 5 (depends on 3) The furniture fitting according to claim 3, wherein the screw has a threaded portion and a head portion connected to the threaded portion, and wherein one of the cooperating tooth arrangements is formed or arranged on the head portion of the screw. ### Claim 6 (depends on 3) The furniture fitting according to claim 3, wherein the screw has a first abutment surface and a second abutment surface spaced from one another in an axial direction of the screw, and wherein one of the cooperating tooth arrangements is a tooth arrangement of the drive element which is received between the first abutment surface and the second abutment surface of the screw. ### Claim 7 (depends on 1) The furniture fitting according to claim 1, wherein the screw is a first screw, and the furniture fitting further comprises a second screw configured to be driven by rotating the tool receiving device with the aid of the tool. ### Claim 8 (depends on 7) The furniture fitting according to claim 7, wherein each of the first and second screws includes a threaded portion with a thread arranged thereon, wherein the thread of the first screw and the thread of the second screw have an opposite sense of helix or a same sense of helix. ### Claim 9 (depends on 1) The furniture fitting according to claim 1, wherein the bearing portion bears against the first housing wall as well as against the second housing wall. ### Claim 10 (depends on 1) The furniture fitting according to claim 1, wherein the screw and the drive element are configured to be moved, starting from the predetermined position, in two directions opposing one another, so that the first housing wall or, alternatively, the second housing wall can be fixed to two different furniture parts. ### Claim 11 (depends on 1) The furniture fitting according to claim 1, wherein the drive element is rotatably mounted about a first rotational axis and the screw is mounted about a second rotational axis, the first rotational axis of the drive element and the second rotational axis of the screw extending substantially parallel to one another. ### Claim 12 (depends on 1) A method for fixing the furniture fitting according to claim 1 to a furniture part, the method comprising: introducing a tool into the tool receiving device of the drive element; rotating the drive element by rotating the tool receiving device with the aid of the tool; driving the screw by the movement-coupling between the drive element and the screw; and fixing the furniture fitting to the furniture part by the screw. ### Claim 13 (depends on 1) The furniture fitting according to claim 1, wherein the screw, after the holding device has been released, is displaceably supported, together with the drive element, relative to the first and second guides of the bearing portion in a direction extending at a right angle to the first and second housing walls. ### Claim 14 A furniture fitting comprising: a rotatably mounted screw for fixing the furniture fitting to a furniture part; and a drive element separate from the screw, the drive element being movement-coupled to the screw, wherein the drive element includes two tool receiving devices having respective openings which face in opposite directions, wherein the drive element and the two tool receiving devices are formed together so as to have a one-piece configuration, and wherein the screw is configured to be driven by rotating either of the tool receiving devices with the aid of a tool.
