you don't need any special screws for this, you can probably get items cheaer at your local hardware store?

the cable is the hardest thing to run in plaster walls, with plaster running out behind lathing boards and insulation if any?

you need, an old work receptical box, and two Madison bars. cut your hole to fit the box only 2x3"? leaving the top and bottom flanges out of wall, insert box, and fasten with Madison bars. the screws come with the wall plate.

I would think drywall screws would be the best to use. Get those that have finner thread so that yo have more contact area.

I have tried just using screws - but they eventually pull out. I recommend plastic anchors.

plaster, is simply just too brittle for any kind of screw. as the screw goes in, it pulverises the plaster into powder.

unless you are lucky enough? to have the old wooden lathing behind your plaster, you might get lucky and screw into the wooden lath with longer screws. if not? you're going to have to use some kind of expansion anchor. the plastic ones might work? if you can drill a good smooth hole in plaster?

I'd cut the head off the plastic anchor, and try to get end of anchor slightly below the surface of plaster in order to get the wall plate in tight to the wall. those heads seem to stick out a bit!
