Grobet Nut and Screw Grabber

With an expandable jaw, this driver automatically grips any size or shape of lock nut, hex nut, star nut, cap nut, or round nut. Also doubles as a screw starter. Placing a screw in the self-closing jaws makes it easy to thread even the smallest screw in to the hardest to reach place. The more pressure you apply, the tighter the grip on the screw.
