Abstract
A trailer hitch ball for use with a trailer hitch, a lock housing, a lock washer and a nut. The trailer hitch ball can be used to secure a trailer to a vehicle. The hitch ball includes a ball portion, a base portion and a threaded portion. The ball portion includes an integral drive member such that when torque is applied to the drive member, force is applied to the ball portion and the ball portion rotates relative to a trailer hitch. The outer surface of the ball portion may define two parallel and opposing tool engaging surfaces. When a trailer coupler is locked to the ball portion, the trailer and trailer hitch ball are secure from theft.
