T40060 42MM x 2 Stud Driver
The T40060 is used to drive the stud into the main frame. The outer diameter is threaded onto the stud and advanced until it is secure but not bottomed. The small bolt is then advanced to prevent the tool from bottoming on the larger threads. With the tool secure on the stud a wrench or socket is used on the outer hex to tighten the stud to the main frame. When tight the small bolt is backed off and the tool can be easily removed.
