I wander if someone could answer this question for me , as slightly confused . Before anyone said’s any think haha its nothing to do with cross threading as I know how that is caused now . However the other day I was at the pub and my friend who is a apprentice mechanic , said to me that the bolt will sit flush if you were to force it in all the way but surely as it is at angle due to cross thread it will be at a slant and wont sit right . The only think I can think off is that your bending either the threads or the bolt it self to go in flush.
Wandered if you think it true or false
