Abstract

Abstract An aligning apparatus for inserting a bolt and a washer in a remote or reicted place for securing equipment. A standard washer is permanently attached to the end of tubing, a bolt is inserted in the tubing through the washer and held in position by a tool inserted in the tubing, mating with the bolt. This combination is placed in alignment with a normally inaccessible threaded hole. The bolt is turned into the hole and secured by a torquing action on the tool. For the reverse process, removal tabs are attached to the tubing to accomplish intact extraction of the bolt, washer, and tubing.
