When installing the Curt Trailer Hitch Receiver part # 13333 you will use a half inch hex bit or allen. Generally in this case we use an impact type 1/2" hex bit on a large torque wrench. This tend to let us get tot he high torque spec of 320 ft./lbs. required.

A 3/4" or 19mm is also required as a heads up.
