I have a door that was slightly tilted and didnt close properly. I noticed the hinge was a tad loose, and what was holding it was a short 0.5" screw. I replaced it the screws with a new 1" screw and the door was ok for a couple weeks. But now its tilting sideways again, and the screws are loose again.
I assume that the screw holes are worn out and thus do not hold the screws well, and gave up.
The door, and the door frame, is a regular standard US wooden door. The hinges are common as well. Not familiar with exact model, type, or naming convention. In the images you can see the hinge tilting sideways, as well as it pushing the screws out from the screwholes.
I was thinking about using screw anchors. But what other methods are there to fix a loose screw hole?
