Used primarily for mounting in walls that consist of plaster. The assembly is a bit tricky, so please follow these steps. First step, drill a hole using a drill, the size of the drill is the same as the expander's size name. Next, hammer the molly plug with a hammer. Next, take a screwdriver and screw in the screw so that it expands behind the plasterboard, so you screw until you notice that it gets hard and almost stops, if you screw too long and too hard, the plasterboard will break, so stop screwing when you feel noticeable that it pinches.
