G`day
Only trying to be helpful but it doesn`t always work out that way and i see your point it doesn`t go with the rest . I can`t edit it sorry .
Have you tried , sharp tapping it and have you tried going the other way both can help . ( not questions )
If you can get a 1/2 inch breaker bar on it and it won`t move you do have a problem , use a piece of pipe on the bar .
