A tool extension for a socket wrench includes a jointed, articulated series of square-drive male/female adapter ends with intermediate couplers having hex ball-head and socket joints. Three such intermediate couplers together in one series allow for an overall 90-degrees of flex. Each coupler has a bell body over which a pliable control cover is stretched. Each hex ball head and socket joint is bridged over by a corresponding pliable control cover which then snaps over a retaining lip just under a neck.
