An adjustable connection arrangement for axially adjusting a threaded toolholder with respect to a quick change adapter to preset the tool with respect to the machine spindle including an adapter nut releasably secured to the quick change adapter and having a bore formed therein in which the OD of the threaded toolholder slidingly fits to insure a minimum runout therebetween. An internally threaded split retaining ring is positioned in an annular groove intermediate the adapter nut bore and disposed to threadedly engage the toolholder, while a set screw carried by the adapter nut is provided to compress the split retaining ring and lock it to the toolholder threads in any adjusted position to thereby create an axial adjustment and locking arrangement between the toolholder and adapter nut without excessive runout.
