A wall plug is used to ensure screws driven into concrete provide a secure fixing. Without them, screws would not grip into concrete and would not provide adequate compressive force to ensure a secure, permanent fixing.
Installation usually involves ensuring first that the correct size plug is paired with the screw. As the screws must fit inside the plug, the hole to be drilled will be larger than it would be for the screws. The plug is inserted into the drilled hole and the screws is driven into the plug. As the screws penetrates the plug, it gradually forces the plug sides to expand outward, applying a compressive forces against the concrete. The screws is tightened until it has fully penetrated into the plug, at which point it cannot be tightened any more.
Sometimes the screws turns indefinitely without tightening. This usually means the wrong size of plug has been used or the hole drilled is too big for the plug.
