I'm required to change license plate every few years.
Today when I replace the front plate, I noticed the screws are not very tight. They are just 3/4 inch long pan head sheet metal screws screwed directly into the front bumper. I'm afraid to tighten it too much because it may strip the "thread" in the bumper.
I put some loctite on the screws, but I'm not sure loctite works on sheet metal screws.
What's the best solution?
Aside from the holes made by the two screws, there are two pre-punched round holes almost 1cm diameter on the front bumper near the two screws. They are spaced about 1 inch further apart than the license plate screws. What are these holes for? Is there a subaru license plate holder that uses these holes? I searched in subaru parts web site and didn't find any.
The rear plate is different. There are two holes with plastic anchors for the sheet metal screws to bite into, and spaced just right for the license plate.
