A screw element includes an outer radius Rand a core radius Rfor multiscrew extruders with co-rotating and intermeshing screw shafts. The screw element has in axial cross section through its longitudinal axis a profile which has at each of the two axial end faces (i.e. a front end face and a rear end face) only one screw flight corresponding to a conventional single-start screw element for intermeshing screw shafts. In this case, the width (flight land angle &#x3c6;) of the screw flight and conversely, in a corresponding way, the width (flight land angle &#x3c6;) of the screw flight are formed in a special way and a shearing flight with a constant shearing flight radius R, which is greater than R, and less than R, is provided.
