Abstract
Adjustable fastener tools are provided for engaging socket heads. The tool includes a support member, multiple engagement fingers, and an adjustment mechanism. The support member has multiple radially-extending tracks, and a central opening, and the fingers are associated with, and slidable along, the radially-extending tracks. The fingers include at radially inner ends jaws with respective contact surfaces for engaging the socket head. The adjustment mechanism resides, at least in part, within the central opening in the support member, and couples to the fingers. The adjustment mechanism includes an actuating member and multiple hinged trusses. A hinged truss of the trusses is hingedly coupled at one end to the actuating member and hingedly coupled at an other end to a respective finger of the engagement fingers. Movement of the actuating member results, via the hinged truss, in slidable movement of the respective finger along its associated radially-extending track.
