1. A tool for removing a threaded insert from a supporting wall structure, the threaded insert having a flange and an internally threaded barrel extending from the flange, the tool comprising:
a bracket comprising:
a structure supporting arm having a hole formed therein, the hole shaped and sized to receive the flange of the threaded insert, and to accommodate translation of the threaded insert through the structure supporting arm;
a plunger positioning arm having a threaded hole formed therein;
a connecting section coupling the structure supporting arm to the plunger positioning arm, wherein at least a portion of the structure supporting arm opposes at least a portion of the plunger positioning arm; and
a gap defined between the structure supporting arm and the plunger positioning arm, the gap shaped, sized, and configured to receive the supporting wall structure; and
a plunger component configured to cooperate with the bracket, the plunger component comprising:
a threaded body configured to engage the threaded hole of the plunger positioning arm;
a pedestal extending from a distal end of the threaded body, the pedestal having a distal end defining a bearing surface that contacts an exposed end of the threaded insert during use; and
a guide tip extending from the distal end of the pedestal, the guide tip shaped and sized to fit within the internally threaded barrel of the threaded insert during use;
wherein insertion of the plunger component into the bracket moves the bearing surface of the pedestal against the exposed end of the threaded insert, continued insertion of the plunger component into the bracket increases force imparted on the exposed end of the threaded insert, and further insertion of the plunger component into the bracket releases the threaded insert from the supporting wall structure to allow movement of the flange of the threaded insert within the hole of the structure supporting arm.
