HELP pulley threads flattened

Help me someone please. what should i do on changin the fanbelt today i struggled to get the pulley nut off and when did noticed the threads were flattend believe this to be y it was so hard to get off.
Problem now is what to do with it, thinking of running a set of 12mm dies over it (might save it)
Any ideas or is it new dynamo..!!!!!
