Abstract
A mechanical locking device for use in attaching the shaft of a golf club to the clubhead. An angle is cast inside the hosel at the base of the hosel bore. The tip of the shaft is cut at an angle matching the angle at the bottom of the hosel bore, such that when the shaft is inserted into the bore, there is no room for lateral movement or twisting of the shaft. This device eliminates the risk that the shaft will separate from the clubhead if the epoxy cement bond should break.
