Abstract: A golf club is comprised of a head including a hollow body having a top wall, a bottom wall, and a front wall arranged for impacting a golf ball. A bore is disposed in the head adjacent a heel end thereof behind the body front wall extending downwardly from the body top wall toward the body bottom wall. A hosel having a generally lengthwise passage is inserted into the bore. The hosel passage is oriented at a predetermined angle relative to a longitudinal axis of the bore, and a tip end of a shaft is received in the hosel passage so that the shaft is disposed at a desired orientation with respect to the head. The hosel is selected from a plurality of hosels with passages disposed at different predetermined angles relative to the bore longitudinal axis. This allows adjustment of the desired orientation of the shaft so that the golf club may be custom fit to a particular golfer.

Abstract: A golf club head includes a heel end, a toe end, a front face arranged to impact a golf ball, and a back face disposed rearwardly of the front face. A perimeter weighting element of increased mass protrudes rearwardly away from the front face and defines a cavity in the back face. The perimeter weighting element includes a top rail and a sole. A plurality of ribs are disposed in the cavity for eliminating undesirable vibrations in the golf club head when the front face impacts a golf ball and for attenuating other vibrations in the golf club head. Each of the ribs extends generally radially relative to the cavity from an inner end to an outer end that merges with the perimeter weighting element. An elliptically shaped geometric mass concentration is formed on a bottom surface of the cavity for assisting the plurality of ribs in eliminating the undesirable vibrations and in attenuating the other vibrations.
