Used for connecting 0.8mm-1.2mm thickness steel studs.
Self drilling drywall screws are mainly used for fastening gypsum boards to metal studs with a thickness of 0.8–1.2mm. With their drill-shaped tail, there is no need to pre-drill during use. This self-drilling design reduces resistance when penetrating steel, allowing for quick installation, saving working time, and improving efficiency.
Common wire diameters include 3.5mm (#6) and 3.9mm (#7), with lengths ranging from 16mm to 70mm. The hot-selling size is 3.5x25mm (#6x1”). Other popular sizes include 50mm plasterboard screws, which are widely used for thicker wall assemblies. As self drilling plasterboard screws, they are ideal for efficient, one-step fastening of board to metal.
