A nut is inserted within a slot formed in the sidewall of a shank member. A hitch pin including a threaded portion for engaging the nut is inserted through the side holes of the receiver tube and the shank member until the threaded portion of the hitch pin engages the nut mounted within the shank member. The hitch pin is then rotated relative to the nut to clamp the shank member against the receiver tube. A lock or clip can be attached to the end of the hitch pin to prevent accidental or unauthorized removal of the hitch pin from the receiver assembly. A bushing can also be used over the reduced diameter portion of the hitch pin after it engages the nut.
