Abstract
A ball hitch and lock assembly is described in which a hitch ball member is connected to the top of a threaded shaft or bolt, the lower end of which is received into a notch of a locking mechanism. A removable locking pin within the locking mechanism extends from one side of the notch, through a bore in the shaft, and into the other side of the notch. The lower end of the shaft received within the notch includes two opposed flats, with each flat being disposed at a respective one of the two opposing ends of the shaft bore. The flats are separated by a distance less than the diameter of the shaft enabling the lower end of the shaft to be snugly received within the notch such that each of the flats interfaces with a respective side of the notch. The shaft threads above the flats extend beyond the width of the notch to prevent the introduction of a cutting instrument for the locking pin.
