I have the old gray plastic boxes the you just push the screw in by hand to install the device. I have several high use outlets that will not stay tight in the boxes now. I have tried, with small sucess, tapping and using 8/32, and have tried caulk. I going to replace all my outlets and switches in the future and was wondering if anyone else has run into this problem?
