ABSTRACT:
In construction of a shell-type golf club head having a cavity and a hosel shaft hole communicating with the cavity, a mass made of solidified low melting point metal or synthetic resin containing dispersed metallic balls is provided at a selected position within the cavity through infusion via the shaft hole. Supplemental mass addition and weight distribution adjustment can be both carried out very simply without any substantial rise in cost. When located on an internal wall of the cavity contiguous to the club head face, the mass provides enlarged sweet spot on the face.
