Abstract

A weight screw for a golf club head having one or more weight ports is disclosed herein. A set of weight screws is also disclosed herein, the set comprising at least one low-weight screw comprising multiple materials and at least one weight screw comprising a single material.

Claims

1. A screw for a golf club head having at least one opening sized to receive the screw, the screw consisting essentially of:

a cap portion comprising a lateral extension region sized to close the at least one opening,

a cylindrical lower portion, and through bore, wherein a width (W_C) of the cylindrical lower portion is between 0.350 inch and 0.800 inch and a thickness (L_B) of the cylindrical lower portion is between 0.010 inch and 0.180 inch; and

a support portion comprising a docking portion, a lateral stop, and a threaded extension portion,

wherein the cap portion is made of a non-metal material,

wherein the support portion is made of a metal material,

wherein the through bore is sized to receive the docking portion,

wherein the docking portion comprises exterior threads,

wherein the through bore comprises interior threads sized to mate with the exterior threads of the docking portion; and

wherein the screw has a mass of less than 2 grams and wherein the support portion has a mass of less than 0.8 grams.

2. The screw of claim 1, wherein the docking portion comprises an engagement bore.

3. The screw of claim 1, wherein the non-metal material is selected from the group consisting of plastic and composite.

4. The screw of claim 3, wherein the non-metal material is injection-molded plastic.

5. The screw of claim 1, wherein the metal material is selected from the group consisting of steel, titanium, tungsten alloy, and aluminum alloy.

6. The screw of claim 1, wherein the cylindrical lower portion rests against the lateral stop.

13. A set of screws, the set comprising at least one screw of claim 1 and at least one screw of claim 7.

7. A screw for a golf club head having at least one at least one opening sized to receive the screw, the screw consisting essentially of:

a cap portion comprising a lateral extension region sized to close the at least one opening,

a cylindrical lower portion, and through bore, wherein a width (W_C) of the cylindrical lower portion is between 0.350 inch and 0.800 inch and a thickness (L_B) of the cylindrical lower portion is between 0.010 inch and 0.180 inch; and

a support portion comprising a docking portion, a lateral stop, and a threaded extension portion,

wherein the cap portion is made of a non-metal material,

wherein the support portion is made of a metal material,

wherein the through bore is sized to receive the docking portion,

wherein the through bore is coated with an adhesive to engage the docking extension, and and

wherein the screw has a mass of less than 2 grams and wherein the support portion has a mass of less than 0.8 grams.

8. The screw of claim 7, wherein the docking portion comprises an engagement bore.

9. The screw of claim 7, wherein the non-metal material is selected from the group consisting of plastic and composite.

10. The screw of claim 9, wherein the non-metal material is injection-molded plastic.

11. The screw of claim 7, wherein the metal material is selected from the group consisting of steel, titanium, tungsten alloy, and aluminum alloy.

12. The screw of claim 7, wherein the cylindrical lower portion rests against the lateral stop.

14. A screw for a golf club head having at least one opening sized to receive the screw, the screw consisting essentially of:

a cap portion comprising a lateral extension region sized to close the at least one opening,

a cylindrical lower portion, and through bore,

wherein a width (W_C) of the cylindrical lower portion is between 0.350 inch and 0.800 inch and a thickness (L_B) of the cylindrical lower portion is between 0.010 inch and 0.180 inch; and

a support portion comprising a docking portion, a lateral stop, and a threaded extension portion,

wherein the cap portion is made of a non-metal material,

wherein the support portion is made of a metal material,

wherein the through bore is sized to receive the docking portion,

wherein the docking portion comprises exterior threads,

wherein the through bore comprises interior threads sized to mate with the exterior threads of the docking portion, and

wherein the screw has a mass of less than 2 grams and wherein the support portion has a mass of less than 0.8 grams.

15. The screw of claim 14, wherein the docking portion comprises an engagement bore.

16. The screw of claim 14, wherein the non-metal material is selected from the group consisting of plastic and composite.

17. The screw of claim 16, wherein the non-metal material is injection-molded plastic.

18. The screw of claim 14, wherein the metal material is selected from the group consisting of steel, titanium, tungsten alloy, and aluminum alloy.
