Suburban Anode Rod Question

[FragmagnetEOD]

Hey all, so I replaced the anode rod and the question I have is this. When I screwed the new one in place, I noticed that I have what to me seams like an excessive amount of threads still showing(3-4). I didn't have any problems starting it by hand or snugging it up with the ratchet. I also got a nice rap of teflon tape going too. I feel pretty confident that it is alright the way it sits, just need some affirmation.
