Abstract
An apparatus is provided for tightening a draw bar, hitch bar or accessory mounting post in a receiver box of a trailer hitch receiver assembly. The apparatus broadly includes a body having an intermediate section with a threaded aperture and a pair of projecting mounting lugs. The apparatus also includes a threaded mounting bolt for engaging the threaded aperture in the body. The body is essentially W-shaped including a pair of shoulders on the intermediate section and a beaded tip at the end of each projecting mounting lug which securely seat and hold the tightening apparatus in the lumen of a tubular hitch bar. The threaded connecting pin is tightened in the threaded aperture in the intermediate section of the body when the hitch bar is positioned in the receiver box in order to tighten the hitch bar against the wall of the receiver box and prevent rattling.
