Abstract
A golf club head (16) is provided with a rough heel end surface (40) that surrounds a threaded opening (38) that enters into the heel (36) of the club head (16) and extends substantially longitudinally of the club head (16). A thin washer (42) is placed against the rough surface (40) then, a similar rough surface (24) on a hosel eye (20) is moved into contact with the opposite surface of the washer (42). A connector bolt (18) is inserted through an opening (22) in the hosel eye (20) and is threaded into the opening (38) in the club head (16). The club head (16) is rotated relative to the club hosel (14) to place it into a desired loft angle. Then, the bolt (18) is tightened. This draws the rough surfaces (24, 40) into tight contact with the washer (42). The surfaces (24, 40) are harder than the washer material and when the bolt (18) is tightened, points or edges on the surfaces: (24, 40) dig into the washer material. This construction allows substantially an infinite number of loft angle settings of the club head (16) relative to the club shaft (12).
