A hollow golf club head made from fiber reinforced plastic is provided with a sole plate of composite construction. The sole plate includes an inner resin block interengaged with an outer metal layer. A projection on the resin block extends upward into an opening in the bottom surface of the club head. An aperture passes through the center of the sole plate and through a nut embedded in the resin block. A threaded bolt is screwed into the embedded nut for weight adjustment.
