I had exactly the same issue… with the bonus of the hole where the tool goes being stripped out.I had tried everything crc etc including trying to rebuild hole with steel kneed it.. Finally got it down today..I ended up getting the hacksaw out and cutting the locking nut off… took some time and effort as had to remove blade from hacksaw to be able to use it otherwise it wouldn’t fit. But i thought that if worst comes to worst I can always get a nut from the hardware shop that will fit the bolt, with the bonus of being able to use a wrench on it and less chance of stripping out another hole and ending up with the same problem… I’m aware this seems a drastic cure but I was at my wits end… at the end of the day it worked… now just need a new nut…
