The package includes: 60 plastic anchors and 60 screws (120 pieces total), providing sufficient quantity to meet various needs. Advantages: Expansion screws can be installed on gypsum board, offering simple operation and clean results, helping save time. Durable: Plastic anchors are long-lasting. The plasterboard self-drilling screw set is made of high-quality stainless steel, providing durability, resistance to breakage, and good corrosion resistance in harsh environments such as high temperatures and cold weather. Perfect design: When tightening the screw, the space in the rib anchor expands on two opposite sides, increasing fixing force. The sleeve features an anti-rotation design that prevents spinning during installation, allowing for quick and efficient screw tightening. Application: Suitable for plasterboard, fiberboard, hollow board, and similar materials. Ideal for installing curtains, lamps, picture frames, ornaments, and other decorative items.
