a first hosel part, having a second serrated surface and a first thread, that fixedly connects to a terminal end of the shaft; and

a second hosel part, having a second thread, that rotatably couples to the anti-rotation device,

wherein the first thread is adapted to engage the second thread to mate the first serrated surface with the second serrated surface to minimize relative rotation between the shaft and the club head; and

wherein the first serrated surface and the second serrated surface are the only contact surface between the first hosel part and the anti-rotation device.

2. The golf club of claim 1 , wherein the anti-rotation device is at least partially enclosed by the second hosel part.

3. The golf club of claim 1 , wherein the anti-rotation device protrudes out from a bottom surface of the second hosel part to infix with the club head.

4. The golf club of claim 3 , wherein the second hosel part has an opening near the bottom surface of the second hosel part, allowing the anti-rotation device to protrude.

5. The golf club of claim 1 , wherein the first thread is an external thread located on an external surface of the first hosel part.

6. The golf club of claim 5 , wherein the second thread in an internal thread, located on an internal surface of the second hosel part.
