Abstract (en)
[origin: US4418590A] The screw assembly comprises a drive unit whose output shaft (14) can be connected with a button die to be applied to a screw head. To prevent the casing (10) of the drive unit from rotating, it is fitted with a retainer (24) which is placed against a solid abutment. The retainer (24) has a ring (23) enclosing the output shaft and being connected via a torsionally elastic element (16) with the casing (10). Torsional deformation of the torsionally elastic element (16) is used as a measure for the torque acting on the screw head. (FIG. 1).
