I removed the screws of the socket (as shown in the image) to check something, and when I tried screwing it back in, the screw wouldn't hold anymore. It just keeps coming off.
I tried sticking the socket back using superglue at the edges, but when I plugged in a water heater and pulled out the plug, the socket got un-stuck again. It's the same with any of the sockets at home. If we remove the screw once, we cant screw it back in again because it doesn't hold.
Is there any way to fix this?
