Abstract
A perimeter weighted golf club head having a flush mounted polymer insert in the club face which is approximately centered coaxially with the center of mass of the golf club head and a cavity filler. A recess for the polymer insert is either formed in the main body structure of the golf club head during the casting process, or subsequently by machining. A retainer is provided to help secure the insert and cavity filler in both the club face recess and the hollow cavity. The retainer can take the form of a through hole connecting the recess to the hollow cavity and/or lip surrounding either or both the recessed insert opening and the cavity opening.
