An Etymological Dictionary of the German Language/Schraube

by Friedrich Kluge

Schraube, f., ‘screw,’ from the equiv. late MidHG. schrûbe, f.; allied to Du. schroef (E. screw), Ic. skrúfa; these terms, some of which may have been borrowed, and hence do not correspond exactly in sound, are essentially ModTeut. Note Suab. schrauf, Bav. schraufen (compared with Swiss štrûbe). Origin obscure.
