if it where an aluminium one you could machine out the hole and press/weld in a bush with new tread ....its iron so welding is nearly impossible , the house itself is realy big and has lots of parts inside so pressing a frosen bush in a heated hole isnt going to work either without damaging the insides , epoxy a piece of pipe with fitting in could work if you can make a strong enough bond .
maibe reaming and tapping the little hole in the bottom and screw in an adapter to the piece you needed to screw in originally ..... if you put teflon tape on the tread it might work if you can tap enough tread in there
