Abstract

A golf club head comprises a body and at least one self-extracting pressed weight assembly. The body comprises a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown. The body defines an interior cavity. The weight assembly comprises at least three components and is configured for a press fit engagement with the golf club head. The assembly has a drive portion and a threaded portion.

Claims

1. A golf club head comprising:

at least one recess for receiving at least one removable weight, the club head defining a threaded opening in a wall of the at least one recess;

the at least one removable weight configured to substantially conform to the at least one recess of the club head, wherein the removable weight comprises

a head defining a socket for receiving an engagement end of a tool;

a threaded body extending from the head and configured to cooperatively engage the threaded opening of the club head; and

wherein the at least one recess having a volume between about 0.3 cm³ and about 15 cm³.

2. The golf club head of claim 1, further comprising at least two recesses for receiving the at least one removable weight.

3. The golf club head of claim 1, wherein the golf club head has a moment of inertia about the head CG (center of gravity) x-axis between about 70 kg·

mm² and about 140 kg·

mm².

4. The golf club head of claim 1, wherein the golf club head has a moment of inertia about the head CG (center of gravity) z-axis between about 200 kg·

mm² and about 350 kg·

mm².

5. The golf club head of claim 1, wherein the golf club head has a volume between about 110 cm³ and about 210 cm³, and a loft between about 13 degrees and about 30 degrees.

6. The golf club head of claim 1, wherein the at least one removable weight ranges from about 1 gram to about 25 grams.

7. The golf club head of claim 1, wherein the at least one movable weight is a weight assembly comprising at least three components.

8. The golf club head of claim 1, wherein the weight assembly comprises a screw, a mass element, and a retainer element.

9. The golf club head of claim 2, wherein the golf club head comprises at least two removable weights, wherein the at least two removable weights are interchangeable.

10. The golf club head of claim 1, wherein the golf club head has a CG (center of gravity) with a head origin x-axis coordinate between about −

4 mm and about 4 mm.

11. The golf club head of claim 1, wherein the golf club head has a CG (center of gravity) with a head origin y-axis coordinate between about 20 mm and about 30 mm.

12. A golf club head comprising:
