How to properly screw in drywall to ensure a secure and professional installation?

To properly screw in drywall for a secure and professional installation, use the correct length of drywall screws, typically 1 1/4 to 1 5/8 inches. Place screws about 12 inches apart along the edges and 16 inches apart in the center of the drywall. Make sure to sink the screws slightly below the surface without breaking the paper. This will create a smooth finish for mudding and taping.
