Question: I’m trying to replace an electrical outlet. As I tried to unscrew the screws holding the outlet to the box, the heads broke off; one is basically flush while the other has a little bit of the shaft still visible.

How can I attach the new receptacle to the box? I don’t feel confident enough to try to drill out the old screws. I’m not sure what to do.

Answer: 
I tried using some PB blaster on the screws, then tried vice grips on the bottom screw. Tried notching the top screw with a Dremel so I could use a flathead on it. These techniques did not work, unfortunately. I’m in a bit of a time crunch, so I didn’t want to try and replace the box and risk having to patch/paint the wall.

I ended up drilling the screws out despite my hesitation. I first used a 1/32” bit, then a 1/16” bit, and finally a 1/8” bit to clean out the holes. The screws were soft enough (likely why they snapped in the first place) that it didn’t take long to drill through them. I swapped out the machined screws on the receptacle with a couple wood screws with coarse threads to grip the plastic. It’s mounted solid and looks great! Thanks for all the suggestions here.
Drill out or remove the old screws with pliers or cut slits with a dremel.

Failing that, remove the old box and replace it.
