ABSTRACT:
Receiver hitch mechanism including a receiver insert is mounted to a vehicle having a receiver type hitch. The receiver insert includes two apertures which a securing pin is indexed through. The first aperture is not within the receiver hitch and contains a threaded interior which coincides with a threaded exterior of a securing pin. The second aperture is located inside the trailer hitch and includes an interior wedge member which extends towards the interior of the receiver insert and is parallel with the securing pin. The securing pin includes one tapered end for frictional engagement with both the wedge member and the interior wall of the receiver hitch, and a second end for grasping, then rotating the securing pin. As the securing pin is rotated and tightened against the wedge member and the interior wall of the receiver hitch, the receiver insert is pressed firmly against the receiver hitch towards the side opposing the tapered securing pin end, thereby eliminating all undesired movement between the receiver insert and the receiver hitch.
