Hello Texas Sailor,
Thank you for your question. The threaded/sweat-on adapter RP12307 comes with the RP17453 and RP17454 tub spouts. The RP5836 Pull-Down Diverter Tub spout comes with a slip on adapter, RP33794 which has a set screw. However, either tub spout will fit as the spout itself is compatible with both adapters.
