I was trying to tie something that has a deep hole (around 7 cm). I tried one screw that has stuck in the middle of the hole. I thought that the screw will come to the end but it didn't as its head is wider than the hole diameter. Now the screw's head is stuck in the middle of the hole while its tip is out of the other side of the hole. I can't get it out or push it further to the other side of the hole. This hole is a simple cylinder.
Any ideas how can I solve this situation? This thing I'm trying to hang on the wall is so important to me.
