Abstract
A method and apparatus for mounting a trailer ball to a mounting platform. The apparatus includes a trailer ball having a threaded stem, a flat washer, and a nut having a plastic collar. The plastic collar includes a ring which is disposed between the nut and flat washer. The ring is formed of a plastic material which is extruded when the nut is tightened sufficiently to provide a positive indication that sufficient tension has been placed on the joint. The method also includes lubricating the stem before threading the nut onto the stem and removing the extruded ring after tightening.
