Abstract: A weighting system for wood golf club heads comprising first, second and third weight receiving sockets and at least one set of removable and interchangeable weights receivable in the sockets. The first and third sockets are disposed in the heel and toe portions of the club head with axes substantially parallel to the face portion. The second socket is disposed between the first and third sockets, with a longitudinal axis substantially perpendicular to the face portion of the club head. The weights are made of materials of varying density. Weighting changes can easily be effected by removing an existing set of weights and replacing them with a set made of greater or lesser density material. Preferably, the weights are screw-threaded into the sockets.

Abstract: A golf club head is provided with sockets generally opposite the club face. The sockets receive removable and interchangeable weights fabricated from materials of varying density. Weighting changes can easily be effected by removing an existing set of weights and replacing them with a set made of greater or lesser density material. Preferably, the weights are screw-threaded into the sockets. A back side of the club head is hollowed in order to concentrate weight at the lowest possible point.
