Winged head screws for installing fiber cement board on galvanized structure - Made in Taiwan Special screws for fiber cement board are available in the following dimensions. 25 * 4.2 each package 800 pieces 32 * 4.2 800 pieces each package 38 * 4.2 700 pieces each package 50 * 4.2 500 pieces each package
Let's refer to the external members of these screws The wings on both sides of the Bradra cement drill are cut with a larger diameter than the diameter of the screw body, and due to its fineness, it breaks when it reaches the profile under the work and the screw is fixed in the metal. This causes the screw to have a movement space of 2 mm inside the cement sheet.
The ends of the screws are not pre-drilled and the screw itself passes through the cement board and metal substructure. n The blades under the screw mud make the screw mud easily buried inside the cement board and do not cause problems in painting operations.
