<p>A golf club 10 commonly referred to as a "driver" includes a head 12 made of titanium and a hosel 14 made of plastic. The head 12 includes a hollow body 18, and the hosel 14 has a lower portion 36 inserted into a bore 28 in the head 12 and an upper portion 34 extending upwardly from a top wall 20 of the hollow body 18. The bore 28 has an open top end 28a that is substantially flush with the body top wall 20 and a closed bottom end 28b that is spaced from a bottom wall 22 of the hollow body 18. A passage 40 extends through the upper and lower portions 34, 36 of the hosel 14 and receives a tip end 17 of a shaft 16 that is preferably made of graphite. Since the hosel 14 is made of softer material than the head 12, the hosel 14 has a cushioning effect on the shaft 16 which reduces the amount of vibration transmitted to the shaft 16. The hosel lower portion 36 has an irregular outside shape and the bore 28 in the head 12 has a complementary irregular inside shape so that the hosel 14 may be inserted into the bore 28 in only one orientation to ensure exact alignment of the shaft 16 relative to the head 12.</p> |
