do they make plugs so that you can simply push 12-2 wire into those holes in the back, instead of using the screws? Because I have alot of them to put in.... thanks Buckman

 

They stopped making 12-gauge backstab receptacles and switches a number of years ago. I think it was U.L. that pulled the plug, but it could have been somebody else.

If you read this or other electrical forums much, you will note that everybody universally condemns that type of connection as being very unreliable. You will also note that many of the problems presented in this forum were caused by those backstab connections.

You can buy receptacles and switches with 12-gauge backwire connections. These are almost as fast as the old backstab connections. Simply strip off some insulation, stick it in a hole in the back, and tighten the screw. It is this last step that makes them so much better than backstabs.
