Replacing electrical outlet mounting screws when threads stripped? ?

Buy an electricians tap screwdriver type.

It has 3 size taps 6/32, 8/32 and 10/32

First retap the hole for 6/32 and if the hole doesn't take a new 6/32 screw go to the 8/32 and tap for that and get an 8/32 screw for the hole.

Most people just use a sheet metal screw or even a sheet rock screw used for metal studs.

The receptacle screws to the box and the plate screws to the receptacle, so as long as the receptacle fits in the box, you are okay there. But you do need to think about the source of the ground for your new outlets. If you have no ground wire in the box now, you can use a pigtail if the box is metal AND its connected to metal conduit and/or boxes all the way back to the panel. You can buy pre-made pigtails with a screw and green insulated wire, pre-stripped and everything. Just screw the attached wire into the back of the box in one of the holes already there, and then attach the bare wire end to your new outlet's ground screw, also green. You mentioned a grounding switch. This is a term I am not familiar with. The light switch will typically operate either a top outlet in a receptacle or an overhead light fixture. It does this by switching the hot or black wire before it reaches the outlet or fixture it is intended to control. You may find that the switch boxes have only two wires and no ground. The same rules apply for adding a ground if your new switch has a ground screw. If the light switch operates the top outlet in a receptacle, you will notice on the old one that the metal tab joining the two outlets on both sides of the receptacle will have been broken, and the box will have two pairs of wires coming in and one pair going out.

If you want to fix the problem real quick just flatten the screw up near where the threads will start going thru the hole in the box ,this makes the screw larger than the screw hole which will now thread into the hole.use a vise or a hammer.

No biggie.

Just get a couple of small self tapping sheet metal screws to fit,

and you're done.

(Do be careful not to cut any wire insulation though.)

just use 2 #8 1" dry wall screws that will solve your problem

it'd be best to get up and go to your nearest hardware store, preferrably one of those mom and pop ones they tend to know more then those young pups at homedepot.

i would go to home depot because i had sort off the same problem and they had something to help.
