Abstract
The sole plate of a hollow metal golf club head includes a pair of V-shaped reinforcing ribs having their spaced apart ends engaging the rear surface of the striking face. The inner ends of the V-shaped ribs engage the front side of a protrusion on the sole plate, and the rear side of the protrusion engages a hollow weight chamber. Another reinforcing rib connects the weight chamber to the rear wall of the club head. A threaded bolt passes through an aperture in the protrusion on the sole plate, and is threaded into the upper portion of the club head, thereby fastening the sole plate thereto.
