Weight member for a golf club head
View Patent ↗A weight member for removable attachment to a weight port of a golf club head is provided. The weight member comprises a head that has a tool mating port for operatively receiving a portion of a fastening tool. The weight member further comprises a shaft that is associated with the head such that the shaft terminates at an end surface. The shaft has a threaded external surface and a non-threaded internal bore that extends from the end surface.
1. A method of manufacturing a kit of weights for removable and interchangeable association with a weight port of a golf club head, the method comprising:
forming a first finished weight having a first finished mass and a second finished weight have a second finished mass different than the first finished mass by:
(a) forming a first intermediate weight body and a second intermediate weight body each having a head and a shaft associated with the head, wherein each of the first and second intermediate weight bodies has a substantially equal shaft length, shaft outer diameter, and head height;
(b) removing, by machining, an amount of mass from the first intermediate body to form an internal bore such that a first mass of the first intermediate weight body differs from a second mass of the second intermediate weight body by a predetermined amount of mass greater than 0; and
(c) configuring the first and second intermediate weight bodies for interchangeable securement within the weight port of the golf club head.
2. The method of claim 1 , wherein step (c) further comprises forming an external threaded surface on the shaft of at least one of the first and second intermediate weight bodies.
3. The method of claim 1 , wherein the first finished mass and the second finished mass differ by at least 3g.
4. The method of claim 1 , wherein the material composition differs between the first and second finished weights.
5. The method of claim 1 , wherein the internal bore is non-threaded.
6. The method of claim 1 , wherein:
the first finished weight further includes a first shaft end and a first head end surface; and
the internal bore extends from at least one of the first head end surface and the first shaft end surface.
7. The method of claim 1 , wherein the first finished mass and the second finished mass differ by at least 1g.
