Drywall screws are used for fastening sheets of drywall to wall studs or ceiling joists. Compared to regular screws, drywall screws have deeper threads. This helps prevent the screws from being dislodged easily from the drywall. Drywall screws are made of steel.
The two common types of drywall screws are the S-type and the W-type drywall screws. S-type screws are good for attaching drywall onto metal. The threads of the S-type screws are fine and they have sharp points to make surface penetration easier.
On the other hand, the W-type screws are longer and thinner. This type of screw is designed for installing drywall onto the wood.
Drywall panels usually vary in thickness. W-type screws are usually driven into the wood to a depth of 0.63 inches while S-type screws are driven to a depth of 0.38 inches.
If there are multiple layers of drywall, then the screw should have a length enough to drive through at least 0.5 inches into the second layer.
Most installation guides and resources identify drywall screws as Type S and Type W. But most often, drywall screws are simply identified by the type of thread that they have. Drywall screws either have a coarse or a fine thread.
