A method of making a golf club head is disclosed. A striking plate is attached to a front open end of a metal casing to cover an opening. The striking plate is placed over the front open end by contacting a rear surface of the striking plate with the front open end, thereby creating a clearance between the rear surface and the front open end. A brazing material is positioned on one of the rear surface and the front open end externally of and immediately adjacent the clearance. When the brazing material melts, it flows into the clearance through a capillary action, thereby forming a layer of brazing material between the rear surface and the front open end.
