For 1/2-inch drywall, the recommended drywall screw size is typically #6 or #8 gauge screws that are 1 1/4 inches long. These screws are designed to securely grip the drywall and penetrate the studs by at least 3/4 inch for a strong hold.
- Coarse thread screws are ideal for wood studs.
- Fine thread screws are preferred for metal framing.
- For ceilings or situations where extra holding power is needed, 1 5/8-inch screws may also be used.
The screw's bugle head design allows it to embed just below the drywall surface without tearing the paper. This size and type help prevent drywall sagging or cracking over time when spaced properly, typically about 16 inches apart along the studs.
In summary, use 1 1/4 inch #6 or #8 drywall screws for 1/2 inch drywall on wood studs, with coarse threads for the best grip. For metal studs, use fine threads in the same size range. 1 5/8-inch screws are an alternative option for added holding power or ceiling applications.
