ABSTRACT:
A hand held tool about the size of a conventional screwdriver that facilitates the installation and removal of circuit board test points. A first socket member at the distal end of the tool engages the outer part of a test point and a second socket member in axial alignment with the first engages the inner part of the test point. The first socket member has an inner diameter greater than the outer diameter of the second socket member so that the second socket member is retractable into the first when the outer and inner parts of a test point are simultaneously engaged by the first and second socket members, respectively. A spring maintains the second socket member forwardly of the first socket member when the tool is not in use. The socket members are independently rotatable under the control of separate handle members.
