Drywall screws are specialized fasteners designed for attaching drywall to wooden or metal studs. They are typically self-tapping, meaning they can create their own hole as they are driven into the surface, making installation faster and more efficient.
Here are some key features and types of drywall screws:
Thread Type:
Coarse Thread: Best for use in wood studs, as the threads grip the wood securely.
Fine Thread: Ideal for use with metal studs or when a more secure hold is needed in thin materials.
Head Type:
Bugle Head: The most common type, which is designed to prevent tearing the drywall paper. This allows for a flush finish.
Flat Head: Sometimes used, but less common for drywall installations.
Finish:
Phosphate Coated: Provides a protective layer that helps prevent rust, commonly used in dry indoor environments.
Zinc Plated: Offers greater rust resistance, especially in more humid conditions.
Black Oxide Coated: Provides an even more durable finish and corrosion resistance, typically for more demanding environments.
Length:
Typically range from 1” to 3” in length, depending on the thickness of the drywall and the material being fastened.
Sizes:
Drywall screws come in different gauges, with the most common being #6 and #8.
