A modern version of the famous "Johnson Bar", known to veteran aircraft mechanics a the go-to tool when you want to remove a stuck or partially stripped panel screw without damaging the aircraft skin. The T-Bar works by mounting to an existing nutplate and using it as a leverage point to remove the problem screw. Simply screw the anchor tip into the nutplate thread, adjust the hex driver to engage the screw head, then bear down on the lever and twist the T-handle to remove the frozen screw. A must-have for every mechanic.
