The thick metal plate has a thread for two bolts. By mistake I screwed one of the bolts in all the way. Now the bolt won't come out from the metal plate - bolt spins freely both directions. I tried to apply downward force on plate while turning the bolt in hopes that it will "catch on thread", but it didn't.
Any tips on how to get the bolt out? And is the thread most likely ruined in the plate and/or bolt?
P.S. this part is from washing machine where it goes into trunnion.
