The T40060R is used to remove the studs from the frame. It is also threaded onto the stud and when secure, but not bottomed, the smaller bolt is then turned in the counter-clockwise direction. The bolt features a left-handed thread so the counter-clockwise rotation will force the stud to loosen from the frame. When the stud is removed the bolt is turned in the clockwise position to unseat the tool from the stud and then the tool is removed normally.
