Abstract
Clubs and clubheads are disclosed that allow the swing-weight thereof to be easily changed by attaching or exchanging a “weight-assembly” having a first portion configured as a “weight insert,” a second portion configured as an overcap, and a third portion configured as a drive screw. The drive screw extends through the overcap and into the weight-insert to assemble the weight-assembly, which fits into a weight-receiving cavity on the clubhead. These three components are made of respective materials (having respective densities) that are selected so that each component contributes a desired fraction of the total mass of the weight-assembly to the clubhead to achieve a desired change in swing-weight. By mix-match selection of the components, a wide range of masses of the weight assemblies can be made, with small increments therebetween.
