Abstract

A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ΔCGz) that is less than 2 mm.

8. The golf club head of claim 6, wherein the weight installation cavity includes at least one recessed surface that extends longitudinally over at least a portion the channel.

9. The golf club head of claim 6, wherein the outer member and the inner member are noncircular and are shaped to prevent rotation when the threaded fastening bolt is tightened.

10. The golf club head of claim 9, wherein when the at least one weight member is secured to the channel the outer member engages an outward-facing surface of the at least one ledge and the inner member engages an inward-facing surface of the at least one ledge, and the threaded fastening bolt has a threaded shaft that extends through a first aperture of the outer member and engages mating threads located in a second aperture of the inner member.

11. The golf club head of claim 6, further comprising a plurality of projections located on the at least one ledge, wherein the plurality of projections have a size and shape adapted to help locate the at least one weight member along the channel.

12. The golf club head of claim 6, further comprising a heel opening located on a heel end of the body, the heel opening configured to receive a fastening member;

and
