You need to change the shower arm!
It is a simple procedure and costs less than one container of CLR.

Hi

What's the best way to clean rust & hard water grime off a pipe thread in
the shower? I need to replace the shower head, but the replacement bits
won't fit, despite the thread being the same size.

Any ideas? I'm onto my second application of CLR, don't know what to try
after that.
