7. The golf club head of claim 5 wherein the second scallop is aligned with one of 45°, 135°, 225°, and 315° positions within the coordinate system.
8. The golf club head of claim 1 , wherein the at least one rib extends over the at least one scallop.
9. The golf club head of claim 1 , wherein the body has an average thickness of approximately 0.032 inch.
10. The golf club head of claim 1 , wherein the at least one rib has an approximately triangular cross-sectional shape.
11. The golf club head of claim 1 , wherein the at least one rib has a thickness of 0.030 to 0.090 inch.
12. The golf club head of claim 1 , wherein the at least one rib comprises three ribs.
13. A golf club head comprising:
a body comprising a face section, a crown section, a sole section, a hosel, an interior cavity, a flange where the hosel joins with the crown section, face section, and sole section, a reinforcement region proximate the flange, and a volume of 50 to 300 cubic centimeters;
at least one rib; and
at least one scallop;
wherein the hosel comprises a hosel bore with a hosel axis and a hosel embedment, wherein the hosel embedment extends into the interior cavity of the body below the flange,
wherein each of the at least one rib and the at least one scallop is confined to the reinforcement region,
wherein, when a coordinate system is applied to the body and centered around the hosel axis, 0° and 180° positions extend parallel with the face section and 90° and 270° positions extend perpendicular to the face section, wherein the 0° position extends toward a heel side of the body and the 180° position extends toward a toe-side of the body, with the 270° position extending in a forward direction away from the face section and 90° position extending rearward from the face section, and
wherein the at least one rib extends from the hosel embedment onto an inner surface of the crown section and is disposed entirely between the 90° and 180° positions of the coordinate system;
wherein the reinforcement region is located between the flange and the face section, between the flange and the sole section, and between the flange and the crown section.
14. A golf club head comprising:
a body comprising a face section, a crown section, a sole section, a hosel, an interior cavity, a flange where the hosel joins with the crown section, face section, and sole section, a reinforcement region proximate the flange, and a volume of 50 to 300 cubic centimeters;
at least one rib; and
at least one scallop;
wherein the hosel comprises a hosel bore with a hosel axis and a hosel embedment, wherein the hosel embedment extends into the interior cavity of the body below the flange,
wherein each of the at least one rib and the at least one scallop is confined to the reinforcement region,
wherein, when a coordinate system is applied to the body and centered around the hosel axis, 0° and 180° positions extend parallel with the face section and 90° and 270° positions extend perpendicular to the face section, wherein the 0° position extends toward a heel side of the body and the 180° position extends toward a toe-side of the body, with the 270° position extending in a forward direction away from the face section and 90° position extending rearward from the face section, and
wherein the at least one rib extends from the hosel embedment onto an inner surface of the crown section and is disposed entirely between the 90° and 180° positions of the coordinate system;
wherein each of the at least one rib and the at least one scallop is spaced from and does not make contact with the face section.
