A relatively recent innovation is the self-tapping screw anchor, which can work very well for certain wallboard applications when they are installed correctly and used in their intended way. Self-tapping anchors avoid this with the use of an anchor sleeve with large threads that can securely grip the core of wallboard panels. Into this sleeve, anchoring screws are then driven with a screwdriver.
