DAGGERZ CEMENT BOARD SELF DRILL SCREWS - 8 x 2-1/4

Using these Daggerz cement board self - drill screws is easy. First, make sure the surface of the metal and cement board is clean. You don't need to pre - drill holes in the metal because of the self - drill point. Just align the screw with the spot you want to attach and use a #2 Phillips driver to turn it in. The wafer head with nibs will prevent the screw from spinning and help it sink in nicely. When it comes to maintenance, since these screws have a 1000 - hour salt spray coating, they're quite resistant to corrosion. But if you notice any signs of rust in a very harsh environment, you can use a mild rust remover. Store the screws in a dry place to keep them in good condition. Also, be careful not to overtighten the screws as it might damage the cement board or the screw itself.
