<p>Disclosed is a tool (20) for grasping a nut (9) and initiating the threading of the nut (9) to a difficult-to-access threaded counterpart element (28). 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 mount (5a) with the nut disposed in an orientation that enables it to be positioned in the socket (28). The socket body (1) is connected to a flexible arm (11) having a passageway (33) extending through 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 turned and twisted relative to each other to configure the arm (11) to reach the socket (28).</p> |
