A hand-held drive-in tool for driving fastening elements ( 60 ) in a workpiece (U) includes a drive-in ram ( 13 ) displaceable in a guide ( 12 ), a spring ( 31 ) for driving the drive-in ram ( 13 ), a tensioning device ( 70 ) for loading the driving spring ( 31 ), a locking device ( 50 ) for retaining, in its locking position ( 54 ), the driving spring ( 31 ) in its loaded position thereof ( 33 ), and a sliding nut ( 78 ) supported on a threaded spindle ( 76 ), which is rotatable by the motor ( 71 ) of the tensioning device ( 70 ), without a possibility of rotation thereabout but with a possibility of an axial displacement therealong, the sliding nut ( 78 ) being axially displaceable, upon actuation of the motor ( 71 ) of the tensioning device ( 70 ) by a control unit ( 23 ) of the drive-in tool ( 10 ), from the first end position ( 83 ) to the second end position ( 84 ) for displacing the driving spring ( 31 ) into the loading position ( 33 ) of the driving spring ( 33 ), and being subsequently displaceable from its second end position ( 84 ) into the first end position ( 83 ) to provide for displacement of the driving spring ( 31 ) to its release position.
