Abstract

The invention provides a golf club head having adjustable weight, allowing the golfer to fine tune the club for his or her swing. The club head includes a body having a ball-striking face, a sole, a crown, and a side extending rearwardly from the face. The body defines an interior cavity and a recess on a selected wall of the body spaced apart from the striking face. A threaded opening is disposed in the recess. The club head further includes a weight assembly having fastener and a mass element configured to be press-fit into the recess the such that a first end is adjacent the bottom of the recess. The mass element also has an aperture configured to receive the fastener flush. The fastener removably attaches the weighting assembly to the selected wall of the club head. Pressure from the fastener attachment provides a press-fit of the mass element in the tapered recess of the selected wall.

Claims

1-21. -21. (canceled)

22. A removable weight assembly for a golf club head, the weight assembly comprising:

a weight body;

a first aperture having a first diameter formed in the weight body;

a second aperture having a second diameter formed in the weight body;

a cavity formed in the weight body, wherein the first and second apertures are coupled to the cavity; and

a fastener having a fastener head and a fastener body, the fastener head having a third diameter, wherein the fastener head is disposed in the cavity, the fastener body extends through the second aperture, and the first and second diameters are less than the third diameter.

23. The removable weight assembly of claim 22, wherein the fastener body is adapted to be removably engaged with a portion of a golf club head.

24. The removable weight assembly of claim 22, wherein the first diameter is adapted to provide tool access to the fastener head.

25. The removable weight assembly of claim 22, wherein a cross sectional shape of the weight body is triangular, hexagonal, oval, or rectangular.

26. The removable weight assembly of claim 22, wherein the weight body has a uniform density.

27. The removable weight assembly of claim 22, wherein the weight body has a non-uniform density.

29. A removable weight assembly for a golf club head, the weight assembly comprising:

a mass element;

a first aperture having a first diameter formed in the mass element;

a second aperture having a second diameter formed in the mass element;

a retaining element coupled to the mass element;

a third aperture having a third diameter formed in the retaining element; and

a fastener having a fastener head and a fastener body, the fastener head having a fourth diameter, wherein the fastener head is disposed in the second aperture, the fastener body extends through the second aperture, and the fourth diameter is greater than the first and third diameters.

30. The removable weight assembly of claim 29, wherein the fastener body is adapted to be removably engaged with a portion of a golf club head.

31. The removable weight assembly of claim 29, wherein the third diameter is adapted to provide tool access to the fastener head.

32. The removable weight assembly of claim 29, wherein a cross sectional shape of the mass element is triangular, hexagonal, oval, or rectangular.

33. The removable weight assembly of claim 29, wherein the mass element has a uniform density.

34. The removable weight assembly of claim 29, wherein the mass element has a non-uniform density.

35. The removable weight assembly of claim 29, further comprising a low friction element disposed between the fastener head and the retaining element.
