To control the shut-off torque used to tighten screws and bolts for manufacturing and assembly. Do not use the digital clutch when tightening screws with a low tightening torque into materials, such as thin plastic. Example application not to be used; When tightening screws into lightweight steel sheet which thickness is 0.8 mm or less. When tightening screws into soft surface materials, such as interior finishing materials. One-shot impact function : C → Set the one-shot impact function to tighten screws slightly to adjust the screw head flush to the material surface. Select the clutch setting to match the application. This is used when readjusting is continuously required. The driver automatically rotates approximately half round and stops each time the trigger switch is depressed.
