Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged andor so that the shaft position with respect to the club head can be readily changed. The method checks an address record for an associated cleansing date. The method further includes providing the metallic member with an intervening layer of metal having an ionization tendency between an ionization tendency of metal constituting the first plate and an ionization tendency of metal constituting the second plate, and the first plate and the metallic member are joined together via the intervening layer. In one embodiment, microactuators that are operable to move the microcomponent are controllably deformed to fix the position of the microcomponent at the target position.
