Spouse complained of a loose outlet. It turns out that holes in the box for
mounting the outlet are broken out. The box is a gray plastic one and the
6-32 screws do not have anything to bite into as the wall that forms the
hole is broken.

I am not sure if there is enough material left to try to use an 8-32 screw
instead without breaking off more of the wall that forms the screw hole.

I sure don't want to have to remove the box and replace it, The box is side
mounted to a stud and it is in a finished wall.

Any suggestions for a "quick fix"? are there any epoxies that can be used
fill the space so I can retap the hole?

I have JB weld and a stick of the so called plumber's epoxy, but I am not
sure that they would stand up to drilling and retapping and have enough
strenghth to hold the screws without pulling out.
