ABSTRACT:
A tool which has the capability of removing the nut from both large and small nut plate assemblies, the tool also including a portion for installing a nut into the plate assembly cage. The tool comprises a handle having a removal nose portion at one end and a threaded shaft portion for receiving a reinstallation socket at the other end. In a preferred embodiment, the portion of the handle incorporating the removal nose portion is angled with respect to the remaining portion of the handle. The reinstallation socket has a threaded aperture for receiving the thread shaft portion, therefor securing the socket to the tool. The nose portion has an upper jaw portion separated from a lower jaw portion by an opening. The upper jaw portion is used to pry open the nut plate cage and the lower jaw portion pushes and lifts the nut from the cage. The space between the two jaw portions enables a pivoting action around the pried open cage wall.
