More likely, the threads just need some clean-up. The best way to do this is with a thread file:
If you're carefull, a triangular file can also work.
Thank you, i don't have a thread guage or thread files.
I shall just try to clean the gunk out of the threads with a wire brush and if need be go to my lbs and use their files.
