A threaded element (1) is provided having at least two slots (3), notches, grooves or the like that intersect the thread (2). The slots (3), notches, grooves or the like are configured in relation to the thread (2) so that they intersect the thread (2) to form a sharp cutting edge on the thread flanks (4), thus preventing reverse rotation. The slots, notches or grooves have no more than 25-times the pitch and the same rotational direction as the thread.
