Depending on your skills and your reliance on this stove, it might be worth ordering a new latch and nut, so as to not risk downtime if things don't go right while repairing this one. Shouldn't be more than a few dollars, I'd guess.
I have the the tools needed to get the job done. Def gonna order the item tho as mistakes can and do happen, Just curious that this has happened to me twice the first time tho i snapped the bolt.
