Tamper resistant security srews for faceplates, wall jacks, outlets, switch plates and more. There are a few common types of tamper resistant screws in use.  Most common is the torx security type which is a torx drive with a pin in the middle.  Usually a faceplate screw is a 6-32 thread and if you are using a flat torx security screw, you would likely use the #T-10 with the recess for the pin.  Another very common tamper proof screw is the spanner or snake eyes.
