Wall plugs 8mm are small, cylindrical plastic anchors used to securely fix screws into solid walls like concrete, brick, or plaster. Designed to expand when a screw is inserted, they grip the surrounding material tightly, providing a strong and stable hold. The 8mm size refers to the diameter of the hole needed for installation, making them suitable for medium-duty applications such as mounting shelves, brackets, or light fixtures. They ensure that screws don’t loosen or damage the wall surface over time.
