A temporary shaft-component connection for assembling a selected golf club shaft with a club head and/or hand grip segment, to facilitate custom club design and fitting to suit the needs and preferences of an individual golfer. The temporary shaft-component connection is particularly designed for use with nonmetallic club shafts formed from a graphite-based composite material or the like having a range of different lengths and stiffness (whip) characteristics. The temporary connection includes an adapter insert for slide-fit reception into an adapter socket, wherein the adapter insert and socket include interengaging flat surfaces such as splines to prevent relative rotation therebetween. The adapter insert is mechanically seated and secured relative to the adapter socket at a pair of axially spaced locations, with a resilient compressible anchor member disposed at one of these securement points for substantially eliminating undesired intercomponent movement.
