Claim:
1. A selectable weight assembly for insertion into a golf club shaft comprising: a retaining screw, a primary weight, and a bushing, and coaxially assembled along a major axis corresponding to the central axis of said golf shaft interior; said retaining screw comprising a screw head and a shaft; said primary weight adjacent said retaining screw, said primary weight having an upper end and a lower end, said primary weight including a hollow interior extending therethrough for receipt of said shaft of said retaining screw, the lower end of said primary weight having a slug section, said bushing adjacent said primary weight and composed of elastic, compliant material, and affixed to and encompassing the end of said primary weight, said bushing of a first untensioned width slightly greater than the width of the shaft at a selected depth; whereby the threaded shaft is engaged through said interior of said primary weight through, deforming said bushing such that its width decreases under the applied axial force, and upon removal of the applied axial force, returning the bushing to its untensioned state, providing an expansive force for secure frictional contact with the interior surface of the shaft.
