an internal receptacle, and

a through bore,

a weight adapted to engage said internal receptacle, and

a fastener, adapted to engage said through bore of said cover to secure said cover to said body portion,

wherein said cover completely conceals said weight from view when said weight is installed within said internal receptacle, and

wherein said fastener moves along a weight axis, and,

wherein said weight axis forms an angle α with said striking face plane of between about −10 degrees to about +10 degrees.

10 . The golf club head of claim 9 , wherein said angle α is between about −5 degrees and about +10 degrees.

11 . The golf club head of claim 10 , wherein said angle α is between about 0 degrees and about +10 degrees.
