A device for altering the angle between the shaft and the head of a golf club. The preferred embodiment of the invention utilizes a plurality of inserts which are configured to be inserted into a tapered hole in the golf club head for receiving a shaft or a hosel for mating with the shaft. Each such insert is designed to provide a different angle between head and shaft so that the golfer merely selects one of the plurality of inserts which will be best for his or her hitting accuracy. The inserts are positioned in the club head in such a way as to create a swaging of the insert into the club head and the insert onto the shaft tip. Swaging is the interference fit of two components with two or more surfaces that are forced together in a locking condition, for instance a tapered pin into a tapered hole. A swaging screw is utilized to drive the insert into a tapered swage condition with the club head and thus squeeze onto the shaft to ensure a strong bond without utilizing an adhesive. The disclosed embodiment relates to a golf club putter, but other golf clubs, such as metalwood head golf clubs would employ the invention as well.
