An assembly unit (1) includes a component (2), one ore more screws (3) and bushes (18). The screw (3) includes a shank (5) at least partially including a thread (10), a head (4) being designed and arranged to rotate the screw (3) and a supporting surface (6) facing the component (2). The supporting surface (6) is designed and arranged to directly contact the component (2) after assembly without contacting the bush (18) to transmit an axial force. The component (2) includes a through hole (17) for each screw (3). The bush (18) is associated with the screw (3), and it is designed and arranged to be fixedly connected in the respective through hole (17). The bush (18), the screw (3) and the component (2) are designed and arranged to be locked and aligned in an axial direction. This is achieved by the diameter of the through hole (17), the outer diameter and the inner diameter (28) of the bush (18) and the shank (5) of the screw (3) being designed and arranged with respect to one another in a way that the screw (3) after its pre-assembly protrudes through the through hole (17) in a fixed manner.
