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:

a body comprising 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, wherein the body defines an interior cavity;

at least one self-extracting pressed weight assembly comprising at least three components and being configured for a press fit engagement with the golf club head, the assembly having a drive portion and a threaded portion,

wherein the golf club head has a volume between about 250 cm³ and about 500 cm³, a coefficient of restitution greater than about 0.8, and a loft between about 6 degrees and about 16 degrees.

2. The golf club head according to claim 1, wherein the at least one self-extracting pressed weight assembly is a first assembly, further comprising a second self-extracting pressed weight assembly positionable at a location on the golf club head spaced apart from the first assembly.

3. The golf club head according to claim 1, wherein one of the at least three components of the self-extracting pressed weight assembly is a screw.

4. The golf club head according to claim 3, wherein the screw comprises the threaded portion and a head with the drive portion.

5. A self-extracting weight mass assembly for a golf club head having at least one recess for receiving a removable weight mass assembly, the club head defining a threaded opening in a wall of each recess, the weight mass assembly comprising:

a fastener having a head and a threaded body extending from the head, the head defining a socket, the threaded body configured to engage the threaded opening of the golf club head;

a weight element dimensioned for press fitting into the recess, the weight element being positionable about the fastener and having an upper end and a lower end, the mass element defining a bore sized to allow the threaded body of the fastener to extend out of the lower end while inhibiting the head of the fastener from passing through the bore; and

a retaining cap attached to the upper end of the mass element such that the head of the fastener is captured therebetween, the retaining element defining an aperture aligned with the socket of the fastener.
