I recently purchased a shaft(with adapter) to put in a 915H 18* 2 hybrid. The shaft was listed as " 19* hybrid shaft w/adapter". The adapter fits into the club head but when the screw is tight the head is still loose. I think the screw is too long and bottoms out in the adapter before actually tightening the club head. Is there a reason for this and is there a possible fix for this problem?
