ABOUT THIS CATEGORY
Wall plugs are plastic or steel inserts used to affix screws in porous or brittle surfaces like cement and plasterboard where a screw is unable to adequately grip. The most common wall plug used for cement, bricks, and blocks are a tapered plastic tube. These wall plugs are insterted into a hole and are then expanded by driving an appropriate screw in. This causes the plug to expand and press itself against the sidewall of the hole to support the weight of the object being supported. For softer walls like plasterboards, a screw-like insert is driven in a pilot hole that in turn accepts an appropriately sized screw. Wall plugs are available in different sizes and lengths.
