Black drywall screws are a type of fastener specifically designed for use with drywall. These screws come in various sizes and styles, with the most popular being black drywall screws for ceiling applications. These screws are made from hardened steel that is black oxide coated for greater corrosion resistance and can be used with both 1/2" and 5/8" drywall. The best drywall screws for 1/2" drywall are typically a course thread, Phillips head screw that is 1 inch in length.
