  • Golf club head and shaft connector
    Patent number: 11167181
    Abstract: A connector forms a releasable connection of a golf club shaft and a golf club head. The connector includes a shaft-mount and a head-mount. The shaft-mount has a first threaded coupling member and a bore that is sized to securely receive the golf club shaft. The head-mount has a second threaded coupling member. The head-mount is sized to be securely received within the bore of the hosel of the golf club head. The first threaded coupling member of the shaft-mount mates with the second threaded coupling member of the head-mount to form a releasable connection of the golf club shaft and the golf club head. The first threaded coupling member of the shaft-mount has dual-handed-thread ability which allows the releasable connection to follow left-handed-thread convention and right-hand-thread convention.
