The invention pertains to a ball joint assembly which includes a ball stud received in a swivel socket of a supporting body. Some of such assemblies are classed as quick disconnects, meaning that the ball stud may be conveniently assembled and disassembled as desired. In another class, the bodies are substantially cylindrical with the sockets forming a pair of diametrically opposed feather edges. In drilling the sockets, it is not uncommon for a burr to be formed about the perimeter, and for this burr to be bent inwardly thereby obstructing the free insertion of the ball stud into the socket. Also it is not uncommon for the feather edges to be bent inwardly resulting in the same problem. By counterboring the socket, the burr is removed and the feather edges are flattened which not only solves the obstruction problem but may also provide other advantages.
