This screw features a color-painted hex head, a sharp point, and a 0.5+2.0mm integrated EPDM bonded washer, with a bright zinc-plated finish. It is primarily designed for fastening low-density, softer materials such as gypsum board, light steel keel, aluminum sheets, and plastic panels. For high-density hardwood applications, pre-drilling is recommended to avoid splitting or cracking of the material.
The painted hex flange head blends seamlessly with surrounding surfaces, enhancing the overall appearance of the installation. This screw offers an excellent price-to-performance ratio and is suitable for general indoor or outdoor use without specific environmental demands.
Popular sizes include 4.8mm, 5.5mm, and 6.3mm, with common lengths such as 30mm, 40mm, 60mm, and 75mm roofing screws. Models like the 10 hex head self tapping screw, 12 hex head self tapping screw, and hex flange head self drilling screw are widely used and readily available.
