Hollow wall anchors are an effective fixing for applications when fixing to hollow and plasterboard walls.
Hollow wall anchors differ from spring toggles in that they grip the wall tightly from both sides. Once fully screwed into position the screw can then be removed, leaving the female socket part of the anchor firmly in place in the wall.
