Abstract
Ledge structure is made integral with a hollow metallic golf club head, to position a metallic sole plate that closes an opening in the bottom wall of the shell. The ledge structure is defined by multiple ledges spaced apart about that opening and in pairs at opposite sides of an upright plane that bisects the head in a front to rear direction. At least two of the ledges are defined by the lower terminals of ribs integrally formed with the head front wall. The ledges are spaced from the outer surface of the bottom wall so that the sole plate outer surface is flush with the outer surface of the head bottom wall; and the sole plate periphery is connected to the rim of the opening in that bottom wall by weld material in the space between that rim and the sole plate periphery.
