So I purchased a new letterbox as the last one I had flap was broken and just keeps flapping in the wind. It all fits apart from when I screw the plates in they just come lose again by a light pull. If you post any kind of parcel the screws come lose. I looked at a few more in screwfix and Amazon and they all had this type of plastic. The one I had previously had a metal thread for the screw and it was solid.
Am I doing something wrong.
