A screwing tool with an output shaft protruding in the direction of a rotation axis from a gear head having a free-run locking mechanism, which output shaft is rotatable in a stepwise manner in a rotation direction by a movement to and fro of a grip arm protruding from the gear head in radial direction, wherein the gear head, a portion of the output shaft adjoining the gear head, and the grip have an electrically insulating casing. In order to further develop such a screwing tool with regard to manufacture and advantageously with regard to use, the invention proposes that the casing has several parts and parts of the casing engage into one another at their sites adjoining one another in the manner of a labyrinth seal.
