Abstract

A golf club head comprising a body with a heel-side sole opening in communication with a hosel bore, a removable shaft sleeve with a tip sized to fit within the hosel bore, and a weight plug sized to fit within, and at least partially fill, the heel-side opening is disclosed herein. The weight plug, which has a base end with a through-opening, a tip end with a flange, and a side opening in communication with the through-opening, is connected to the shaft sleeve with a screw. When the golf club head is fully assembled, a hosel flange is trapped between the weight plug and the tip end of the shaft sleeve, and tightening the screw causes the weight plug and the shaft sleeve to move towards one another.

Claims

1. A golf club head comprising:

a body comprising a sole portion and a heel-side opening extending into the sole portion;

a hosel comprising a hosel bore and a hosel flange extending into and at least partially encircling the hosel bore;

a shaft sleeve comprising a shaft sleeve tip end with an internally threaded opening;

a weight plug comprising a wall, a base end, a plug flange opposite the base end, a side opening extending into the wall proximate the plug flange, and a through-opening extending from the base end to the side opening; and

a screw comprising a head portion, a midsection, and a threaded tip portion sized to engage the threads of the internally threaded opening in the shaft tip end,

wherein the heel-side opening communicates with the hosel bore,

wherein the weight plug is sized to fit within the heel-side opening, and

wherein, when the weight plug is disposed within the heel-side opening and the shaft sleeve is disposed within the hosel bore, the screw connects the weight plug to the shaft sleeve so that the hosel flange is sandwiched between the plug flange and the shaft tip end.

2. The golf club head of claim 1, further comprising a washer disposed between the head portion of the screw and the plug flange.

3. The golf club head of claim 2, wherein the at least one washer at least partially encircles the unthreaded midsection of the screw.

4. The golf club head of claim 1, wherein the plug flange is approximately U-shaped.

5. The golf club head of claim 1, wherein the head portion of the screw is disposed within the side opening of the first weight plug, and wherein the plug flange extends around a portion of the midsection of the screw.

6. The golf club head of claim 1, wherein the base end is angled with respect to the weight plug wall.

7. The golf club head of claim 1, wherein the weight plug has a width that tapers from a maximum width proximate the base end to a minimum width proximate the plug flange.

8. The golf club head of claim 1, wherein the wall of the weight plug has a varying thickness.

9. The golf club head of claim 1, wherein the weight plug has a mass of no more than 10 grams.

10. The golf club head of claim 1, wherein the weight plug follows contours of the heel-side opening.

11. The golf club head of claim 1, wherein tightening the screw causes the weight plug and the shaft sleeve to move towards one another.

12. The golf club head of claim 1, wherein the shaft sleeve is composed of a first material, and wherein the weight plug is composed of a second material that differs from the first material.

13. The golf club head of claim 12, wherein the weight plug comprises a tungsten alloy.

14. The golf club head of claim 1, wherein the base end is approximately flush with an external surface of the sole portion.

15. The golf club head of claim 1, wherein the base end of the weight plug is painted to blend in with an external surface of the sole portion.

16. The golf club head of claim 1, further comprising at least one o-ring, wherein the at least one o-ring at least partially encircles the unthreaded midsection of the screw.
