Blacked drywall screws are the perfect choice for use in drywall installations. They are ideal for hanging drywall sheets and securing them to wooden frames or studs. These screws can be used in building walls, ceilings, and other drywall applications. Furthermore, blacked drywall screws can also be used in the installation of other building materials such as wood, metal, or plastic.Blacked drywall screws have several features that make them stand out from other types of drywall screws. One of the most significant features is their black coating, which provides a sleek and professional finish to the drywall. Unlike other types of screws, which may rust or corrode over time, these screws are resistant to rust and corrosion, ensuring that they remain strong and secure over the years. Additionally, blacked drywall screws have a sharp point, making them easy to start and drive into the wooden frame or stud. They are also threaded all the way up to the head, which provides a tight grip and prevents the boards from shifting over time. These screws are also smooth shank, which helps to prevent tearing of the drywall paper and reduce the risk of bulging or cracking.PL: PLAIN YZ: YELLOW ZINC ZN: ZINC KP: BLACK PHOSPHATED BP: GREY PHOSPHATED BZ: BLACK ZINC BO: BLACK OXIDE DC: DACROTIZED RS: RUSPERT XY: XYLAN Head Styles Head Recess Threads Points
