The Motobilt steel seat belt bungs are used most often for the shoulder mount of your seat belt but can be used for a variety of reasons. These are designed to fit 1.75 inch tubing by simply drilling a through hole and the lip on the end of the bung keeps the bung from pulling through. The thread is 7/16 inch fine thread.
