Abstract
A screwdriver adapter (1) is provided with a receiving part (3) having an interior space (5). At the open end of the pot-shaped receiving part (3) there is inserted a nut-shaped element (2) in torsionally rigid and axially secured relationship. Adjoining the tool driving means (6) there is disposed a channel (8), which passes axially through the nut-shaped element (2) and extends as far as the interior space (5) of the receiving part (3). Drive portions broken off by overtorquing a screw in the tool driving means (6) can travel via the channel (8) into the interior space (5) of the receiving part (3), where they can be collected until an emptying process.
