  • the hosel ring 500 may be other shapes without departing from this invention.
  • the hosel ring 500 may be oval.
  • Another exemplary option set is using four different adjustable loft angles and three different adjustable face angles, thereby creating a club head with a total of twelve different face angle and loft angle configurations.
  • Another exemplary option set is using five different adjustable loft angles and three different adjustable face angles, thereby creating club head with a total of fifteen different face angle and loft angle configurations.
  • Another exemplary option set is using seven different adjustable loft angles and three different adjustable face angles, thereby creating club head with a total of twenty-one different face angle and loft angle configurations.
  • Other configurations of adjustable face angles and loft angles may be utilized without departing from this invention.
  • the splines of the hosel ring 500 and the exterior splines 322 of the hosel adapter 300 may also be configured to engage with each other to thereby limit the number of rotations of the hosel adapter 300 within the hosel ring 500.
  • the spline configuration of the hosel ring 500 and the exterior splines 322 of the hosel adapter 300 illustrated in Figs. 4 and 5 is limited to be rotated in three different rotational positions (e.g., three different loft angles).
  • Fig. 18A illustrates the set of two splines 212al on the shaft adapter 200 engaging the middle two splines 312a on first side of the bore 308 of the hosel adapter 300 with the set of three splines 212a2 on the shaft adapter 200 engaging the middle three splines of the fifteen splines 312a on the second side of the bore 308 of the hosel adapter 300.
  • the shaft adapter 200 is located at the middle rotational configuration and location within the hosel adapter 300.

  • the rotational positions for loft angle may be defined by loft angles starting from approximately 7.5 degrees to 12.5 degrees. Similar configurations of loft angles starting lower and higher may also be utilized without departing from this invention.
  • the club head position and/or loft angle may be adjusted, for example, by rotating the hosel adapter 1300 with respect to the hosel ring 500 and the club head 1102.
  • this hosel adapter offset angle or face angle adjustment may be between 0.25 degrees and 10 degrees, and in some examples between 0.5 degrees and 8 degrees, between 0.75 degrees and 6 degrees, or even between 1 degree and 4 degrees. In more specific examples of the invention, the hosel adapter offset angle or face angle adjustment may by approximately 1 degree or one-half degree offset.
  • the second end 1306 of the hosel adapter 1300 defines a second opening 1310 for receiving a securing member 1408.
  • the second opening 1310 is sized such that the securing member 1408 is able to freely pass through the second opening 1310 to engage the threaded hole 1210 in the shaft adapter 1200.
  • the securing member 1408 also may engage the hosel adapter 1300 at the second opening 1310 (e.g., the second opening 1310 may include threads that engage threads provided on the securing member 1408).
  • the securing member 1408 may also include a spherical washer 1408 A and a screw retention device 1408B.
  • the securing system may also include a screw retention device 1408B.
  • the screw retention device may be located in the club head chamber 1404. Additionally, the screw retention device 1408B may be sized such that the screw retention device is bigger than the mounting plate 1410. The screw retention device 1408B retains the threaded bolt member 1408 and not allowing the threaded bolt member 1408 to fall out of the club head 1 102.
  • Figs. 41A and 41B further illustrate that the first end 1304 of the hosel adapter 1300 includes an expanded portion 1318.
  • the expanded portion 1318 provides a stop that prevents the hosel adapter 1300 from extending into the club head body and provides a strong base for securing the hosel adapter 1300 to the club head body 1 102.
  • the exterior shape of the first end 1304 may be tapered to provide a smooth transition between the shaft 1 106 and the club head 1 102 and a conventional aesthetic appearance.
