Superior quality: our plasterboard wall plugs are made of high quality plastic with self-tapping tips and our drywall self-drilling screws are made of high quality stainless steel, which are strong, durable, comfortably textured and resistant to dislodging breaks. They have excellent rust resistance and superior oxidation resistance to extend the life of the screw. They also have high strength in hot and cold weather and high temperature environments. Bushing inner diameter mm: 8 Easy to use: our fixing plugs have excellent fastening properties. And it is also very easy to use them. All you need to do is drill a hole in the wall to the depth and diameter of the expansion plug. Then tap the expansion plug into the wall with a hammer and tighten the screw clockwise, flush with the expansion anchor. They do not slip off easily and can be removed and reused by simply drilling the hole. Wide range of applications: Our plastic wall expansion tubes are used in a wide range of applications. They can be used indoors or outdoors. They can be widely used for fixing gypsum board, benzene board, decorative board, asbestos board or similar hollow walls. Also suitable for small projects such as fixing picture frames, bathroom or kitchen fittings, shelves, curtain slides, decorative objects, art pendants, lamps, cross-stitch, wall paintings, light mirror cabinets, etc. Superior design: our expansion screw plasterboard is designed with an anti-rotation construction so that the expansion plug does not follow the screw when it is tightened clockwise. With this new anti-rotation technology, it does not rotate with the screw even in softer walls or drilled holes, thus increasing the fixing force. This design is so easy to install and use that even a beginner can easily use our plasterboard wall plugs.
