Claim:
A power tool including a housing, a drive motor, an output shaft, and a power transmission coupling the motor to the output shaft, wherein the housing comprises two separable parts joined together in a rigid connection in a connection area by a threaded joint, and wherein the threaded joint comprises: a threaded tubular connection element arranged to co-operate with internal threads of the housing parts, said connection element having a certain axial extent and comprising: a first thread section for engaging the internal thread of one of the hosing parts; and a second thread section for engaging the internal thread of the other one of the housing parts, the first thread section and the second thread section being axially spaced apart; and a thin walled waist section provided between said first thread section and said second thread section, said waist section serving to decrease the axial stiffness of the threaded joint by increasing the clamping length of the threaded joint.
