DRIVE SOCKET A drive socket for driving a fastener having a head into a workpiece, constructed according to the teachings of the present invention, comprises a movable member having a socket and a sleeve having a bottom end. The movable or socket member is capable of axial movement with respect to a surrounding sleeve. An actuable member connects the movable member to the sleeve. The socket member is offset a distance upwardly from the bottom end of the sleeve. The actuable member positively restricts the axial movement of the movable member with respect to the sleeve so as to permit changing of the distance between the socket and the bottom end of the sleeve from a distance somewhat larger than an axial thickness of the head of the fastener to a distance substantially equal to the thickness of the head in order to fully seat the fastener in the workpiece.
