A method may be utilized to produce a steering spindle part configured as a hollow shaft and having a connecting portion at its end. At least a part of the connecting portion includes increased wall thickness relative to a portion of the steering spindle part adjoining the connecting portion. The method may involve providing a circular, hollow cylindrical tube with an inner surface that is smooth in a circumferential direction, providing a circular, hollow cylindrical sleeve with an outer surface that is smooth in a circumferential direction, inserting the sleeve into an end portion of the tube, and jointly deforming the end portion of the tube and the sleeve such that a flow of material occurs. This flow may form positively locking elements on the tube and the sleeve that engage into one another in the circumferential direction and generate positive locking in the circumferential direction.
