Had to do some plumbing this weekend. One of my hose bibs was failing and it was not repairable. The old piping was polybutelene so I switched out a small section her w pex until we can get the house re-plumbed. I got the Shark Bite connector with on threaded side to connect with the threaded hose bib. The problem is it threaded part is dripping. The threaded sections only mesh about 6 threads but it seems like it should go more. All of the threads are clean. I also added some Teflon tape on the threads. It isn't dripping nearly as bad as the old one so it is still a win in my opinion but I want to stop the drips so I can secure it in the wall. Is it normal for the thread to stick out this far? How much Teflon tape do I need to use? Is that the right thing to use?
Take all the teflon tape off and put new on with more layers ,3 or 4 layers and wrap it on in the direction so it will tighten (wrap tighter) when threading it on. Or you can use a combo of tape and paste. Inspect the threads when apart, some of the new imported "brass" is not of the best quality of brass and machining. Roly
You can still reuse it when the house is re-plumbed.
Anyway, I would take the hose bib off, then use paste. I use paste for metal to metal, and tape for metal to plastic or plastic to plastic. Wrap the tape clockwise around the fitting.

that depends. was it cross threaded? that's hard to tell from a picture. Plumbing threads are usually tapered, so differences in taper can be an issue. I would start with the paste and see if that fixes it.
