A pack of 96 red universal plastic wall plugs (6mm diameter) is a light-to-medium duty masonry anchor designed for secure fixings into all common building substrates. Engineered with a unique expanding geometry, anti-rotation fins, and a collarless design, the plug expands inside solid materials (such as concrete, brick, and blockwork) and forms a firm knot behind hollow walls or plasterboard. Designed to take 3.5mm – 5.0mm (Gauge 6–10) screws, these red universal plugs are the standard choice for mounting light fixtures, shelving, curtain rails, electrical fittings, and bathroom accessories.
