Zusammenfassung:	A screw length determination system capable of quickly determining the length of a screw is obtained. A PLC (10) is equipped with a determination part for measuring the moving speed of a driver for tightening screws in the axial direction of the driver from an initial position until a screw contacts and is screwed into a workpiece, and determining the length of the screw on the basis of the time from the start of movement from the initial position until the moving speed changes.
