The present invention provides technology with which it is possible to highly accurately assess the quality of fastening of a screw. The present invention comprises a position acquisition unit () that acquires the axial-direction position of a driver (), and a fault assessment unit () that assesses that a fault has occurred in fastening of a screw when the amount of change in the axial-direction position of the driver () from when temporary seating occurred is greater than a threshold value. The present invention provides a technology with which the quality of screw fastening can be assessed with high precision.
