Anti-Rotation Design: Our plasterboard wall plugs feature a unique butterfly-shaped anchor that opens to form strong triangular wings inside hollow walls. This creates 360° interior contact, while deep anti-slip threads lock firmly into place, preventing loosening and ensuring safe, long-lasting support for frames and shelves. High-Strength Material: The plugs are made from durable, eco-friendly PP material that resists aging, corrosion, and temperature changes. Paired with zinc-plated self-tapping screws, the galvanized finish offers strong rust and corrosion resistance, making the set ideal for humid areas like bathrooms and kitchens with extended service life. Easy to Install: Simply drill an 8mm hole in the plasterboard, insert the expansion tube fully into the wall, then align and drive the screw until fully tightened. The plug automatically expands behind the board without rotating, giving you a secure, professional-grade fixing with minimal effort and no special tools required. Versatile Applications: Specially designed for lightweight walls such as plasterboard, EPS panels, and other hollow boards, these fixings are ideal for mounting curtain boxes, lighting fixtures, ceiling accessories, photo frames, artwork, and decorative shelves, easily covering everyday household and light commercial installation needs.
