Golf club heads and methods to manufacture golf club heads
Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a putter-type golf club head may include a body portion. The body portion may include a toe portion, a heel portion, a front portion, a rear portion, a top portion, a sole portion, and a weight port. The weight port may have a threaded section and an unthreaded section. A first weight portion may be coupled to the unthreaded section by an epoxy or other adhesive. A second weight portion may be threadingly fastened to the threaded section. The first weight portion may include a central through-bore to provide at least one of air relief or relief for the epoxy or other adhesive. Other examples may be described and claimed.

6. A putter-type golf club head as defined in claim 1 , wherein the first weight portion comprises a first material having a first density, wherein the second weight portion comprises a second material having a second density, and wherein the first density is different from the second density.
7. A putter-type golf club head as defined in claim 1 , further comprising a visual guide on the top portion, the visual guide extending from the front portion to the rear portion.
8. A putter-type golf club head comprising:
a body portion including a toe portion, a heel portion, a front portion, a rear portion, a top portion, and a sole portion;
a weight port in the body portion, the weight port comprising:
a threaded section extending from the sole portion to an internal annular ledge within the body portion;
an unthreaded section extending from the internal annular ledge toward the top portion, the unthreaded section having a first diameter that is less than a second diameter of the threaded section;
a first weight portion coupled to the unthreaded section by an epoxy; and
a second weight portion threadingly fastened to the threaded section and being in contact with the internal annular ledge,
wherein the first weight portion includes a central through-bore to provide at least one of air relief or relief for the epoxy,
wherein a centerline of the threaded section is aligned with a centerline of the unthreaded section, and
wherein the first weight portion comprises a first material having a first density, wherein the second weight portion comprises a second material having a second density, and wherein the first density is greater than the second density.
9. A putter-type golf club head as defined in claim 8 , wherein the second weight portion further comprises a protruding rim extending from a bottom end of the second weight portion, the protruding rim being in contact with the internal annular ledge, and wherein the second weight portion includes a recess in the bottom end defined in part by the protruding rim, the recess being configured to provide at least one of air relief or relief for the epoxy.
10. A putter-type golf club head as defined in claim 8 , wherein the second weight portion further comprises a top end, a bottom end opposite the top end, a protruding rim extending from the bottom end, wherein the protruding rim at least partially defines a recess, and wherein the protruding rim is in contact with the internal annular ledge, and wherein the recess is configured to provide at least one of air relief or relief for the epoxy.
11. A putter-type golf club head as defined in claim 8 , wherein the unthreaded section is a cylindrical section.
12. A putter-type golf club head as defined in claim 8 , wherein at least one of a group consisting of the first weight portion and the second weight portion bears indicia of a mass property.
13. A putter-type golf club head as defined in claim 8 , wherein the first weight portion comprises a material selected from a group consisting of a titanium-based material, a steel-based material, and a tungsten-based material.
14. A putter-type golf club head as defined in claim 8 , further comprising a visual guide on the top portion, the visual guide extending from the front portion to the rear portion.
15. A putter-type golf club head comprising:
a body portion including a toe portion, a heel portion, a rear portion, a top portion, a sole portion, and a front portion having a face portion;
a weight port in the body portion, the weight port comprising:
a threaded section extending from the sole portion to an internal annular ledge within the body portion;
a cylindrical section extending from the internal annular ledge toward the top portion, the cylindrical section having a first diameter that is less than a second diameter of the threaded section;
a first weight portion coupled to the cylindrical section by an adhesive; and
a second weight portion coupled to the threaded section and being in contact with the internal annular ledge,
wherein the first weight portion includes a central through-bore to provide at least one of air relief or relief for the adhesive, and
wherein the weight port is located a distance of less than the second diameter from the face portion.
