<p>Disclosed is a tool 20 for grasping a nut 9 and initiating the threading of the nut to a the difficult-to-access threaded counterpart element 28 which is in a difficult-to-access location. The tool 20 includes a socket body 1 having expandable jaws 5 that have spring action. The jaws 5 terminate in an open mouth 5a having a configuration corresponding to the configuration of the nut 9. The nut 9 is manually inserted into the open mouth 5a with the nut disposed in an orientation that enables it to be positioned in the difficult-to-access socket 28. The socket body is connected to a flexible arm 11 having a passageway 33 extending though it which houses a flexible shaft 34. This shaft 34 is connected to the socket body 1, so that rotation of the shaft rotates the socket body. The arm 11 includes a series of interconnected links 11a which may be turn and twisted relative to each other to configure the arm 11 to reach the difficult-to-access socket 28. The jaws 5 grasp the nut 9, releasably holding the nut until the it is manually screwed to the difficult-to-access threaded counterpart element.</p> |
