Drywall screws,self drilling drywall screw
Drywall screw is a type of building material made from gypsum and other minerals pressed between sheets of heavy paper. It is installed on walls and ceilings using a type of fastener known as a drywall screw. This fastener can be used to secure the drywall to either wood or metal framing members, and is designed to minimize dimpling on the face of the walls. Traditional nails tend to leave small holes in or divots in the drywall, and can even come loose over time. Drywall screws are threaded to grip both the drywall and the framing members tightly, and provide a much more secure and long-lasting installation over time.
In a typical installation, a drywall screw is placed into each sheet every 16 inches (40.6 cm) on center. This 16-inch increment represents the center of each framing member, or stud. After all the screws have been installed, the walls are finished using jointcompound. The joint compound is spread over both the screw holes and the joints between each sheet. Once the compound dries, the walls can be sanded smooth and painted.
The primary benefit offered by drywall screws is their countersunk heads. This means that the entire screw lies flush with the surface of the sheet, creating a smooth and even finish. The countersunk head also helps prevent the drywall screw from breaking the paper surface, a common problem with nails.
