A manually operable tool for driving screws has a drive pinion (3) axially fixed with a housing (1). A spindle (5) in the housing (1) is axially displaceable relative to the drive pinion against the force of a first spring (4). A clutch element (6) is located in a passageway in a collar (20) on the

A manually operable tool for driving screws has a drive pinion (3) axially fixed with a housing (1). A spindle (5) in the housing (1) is axially displaceable relative to the drive pinion against the force of a first spring (4). A clutch element (6) is located in a passageway in a collar (20) on the drive pinion (3) and is radially displaceable by a actuating member (8) for engaging the spindle (5) to the drive pinion. In the engaged position the clutch element (6) sits against a stop surface (9) in the spindle (5). The actuation member (8) is axially displaceable by stops (10, 11) located on the spindle (5) and can be axially fixed to the drive pinion by a retaining element (14) and a snap-element (15).
