Abstract: A metallic ball pin of a ball-and-socket joint, preferably one with high load-bearing capacity, for motor vehicles with a surface ball part 22 containing grooves 60, 62 for receiving lubricant designed at one end of a pin member 10, 30, 40. To improve its functional properties and to reduce its manufacturing costs, a surface ball part 22 with a joint ball surface 25 is molded to a joint ball core portion 16 using an injection molding process.
