A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

A golf club head with a hosel hole cover that helps improve the performance of the golf club head is disclosed. More specifically, the present invention relates to a golf club head having a hosel hole cover at a bottom portion of an interchangeable connection system that not only provides improved performance of the golf club head by strategically utilizing an existing opening to adjust the weighting of a golf club head, but it also improves the aerodynamics of the golf club head by eliminating undesirable recesses that could be detrimental to the aerodynamics of a golf club head.

Disclosed herein are embodiments of adjustable golf clubs comprising features which allow for the adjustment of a lie angle, a loft angle, or both a lie angle and a loft angle of the golf club. In some embodiments, a golf club head includes a body and a hosel, the hosel including an adjustment screw which can be tightened or loosened to adjust the lie and/or loft angles of a golf club head. In some embodiments, certain angles of a golf club head's geometry can be continuously adjustable through a predetermined range of angles.

A golf club head includes a face, a club head body, and a hosel. The hosel has a tubular hosel body extending along a longitudinal axis and defining a bore. The bore is configured to receive a golf club shaft or a shaft adapter. The tubular hosel body is molded from a polymeric material that includes a resin and a plurality of fibers, each fiber has a length of from about 0.01 mm to about 12 mm.

The present invention relates to an iron-type golf club head having a hollow body cavity, a hosel with a shaft-receiving bore that communicates with the hollow body cavity to form a continuous cavity structure, and a center of gravity located closer to the toe than to the heel. The iron-type golf club head preferably includes a face component with a striking face and a rear extending sole portion, and may also include supporting ribs within the continuous cavity structure, a hosel cutout covered by a cover made from a lower-density material than that of the hosel, and through-holes extending through a wall of the hosel.
