Tool For Removal Of Socket Head Screws Having Stripped Heads

摘要

A tool which has a tip with sharp edges and which is adapted to be inserted into the recess of the head of a stripped socket head screw. Once in the recess the tool is rotated to cause tip edges to bite into the internal wall of the recess, so that enough torque can be applied by the tool to the screw head to rotate the screw out of an object with which it is threadably engaged. In one embodiment the tip has an eccentric camming configuration. In a second embodiment it has a split end configuration with the two parts of the end being slidably movable with respect to each other. In a third embodiment the tip has a helical tapered configuration with a polygonal cross-section having sharp facet edges.
