How do you remove a tub spout without screws?

If there is no set screw, you have a threaded tub spout. You can remove your tub spout by twisting it counter-clockwise to see how your existing spout is threaded, if desired, but it is recommended you leave the spout on if you might need to use the tub before your new spout arrives.
