Abstract: The invention relates to a tool, tool, in particular a screwing tool (1), comprising a handle (2), a working part (5) that is connected to the handle and that is used to open or close a threaded connection, and a display device (10) that displays a working value, for example a tightening torque of the threaded connection, wherein the display device (10) has at least two representations of the working value, in particular the tightening torque. In order to develop a generic tool in such a way that incorrect operation can be prevented with sufficient reliability, a covering device (17) is provided, which covers at least one working value and/or is designed in such a way that only one working value can be displayed in the display device (10).

Abstract: The invention relates to a tool with a housing (3) and a handle (2), a working part (5) which is connected to the housing (3) and serves for opening or closing a screw connection and a coupling which has an adjustment (12) and uncouples the working part (5) from the housing (3) when a working value that can be set by way of the adjustment (12) is reached and/or signals the reaching of the working value that can be set by way of the adjustment. Such a tool in which a correct adjustment of the torque value or tightening torque is retained with a high degree of certainty over a relatively long period of time is created by the adjustment having an adjusting screw with a tensioning system.
