short screws are the way to go. and if the end of the screw does stick up a little, paint it black with a sharpie.

If you have an electrician's pliers of the kind which crimps electrical connectors you can probably find a series of threaded holes in it. You can match your screws to the holes and then use the tool to cut the screws to the needed length without messing up the threads. For my money (not a lot of it) the tool would be worth owning even if I never used it for crimping connectors or stripping wire. (Actually, the wire strippers on these are okay but not great. The kind which grabs the wire and pops the insulation is better, particularly with stranded wire.)
