Abstract
The invention is an alternative fitting system for golf clubs including a adapted production head with a threaded hosel and a shaft sleeve adapter and a compression nut. The shaft sleeve adapter is permanently adhered to a golf club shaft. The compression nut holds together the shaft sleeve adapter and the threaded hosel of the club head. Alignment notches on the threaded hosel and alignment features on the shaft sleeve adapter prevent unwanted rotation. Furthermore, some embodiments of the shaft sleeve adapter comprise an angled bore hole, which allows for various loft and lie configurations.
