A method and system for permanently attaching a take-up screw for taking-up the axial clearance of the armature shaft of a windscreen wiper motor are disclosed. The take-up screw is screwed axially into a bore in the motor base (SM) until the screw reaches a stop position in relation to the armature shaft locked in the screw. At least one surface discontinuity is provided in the bore and/or the thread of the screw, allowing the screw to be screwed into the bore until it reaches the stop position. The screw is screwed into the bore until the stop position is reached and a screw- and/or motor base-deformation strain is applied at the discontinuity in order to deform the side surface of the screw and/or motor base (SM) and permanently attach the screw and/or motor base by wedging in the discontinuity.
