Installed a Callaway shaft adapter on a new shaft for Callaway Big Bertha 3 wood.  After install, the screw on the head fits just fine.  However, once turned as far as it will go is is a fraction short of seating properly.  Therefore the head – while attached and not coming off – is lose.  The screw will not tighten far enough.

How did I screw this up?  More importantly, how do I fix this?  By the way, there are two (2) washer on the screw in the 3 wood head.  Just a guess but kit looks like one more washer would enable tightening.  Just a guess though.  I need advice from someone who actually knows what they are doing. : (
