Carbon Steel Black Drywall Screw_ Phillips Bugle Head ST3.5
Drywall screws have deeper threads than regular screws, which prevents them from dislodging easily from the drywall. They are made of steel and require a power screwdriver to drill them into the drywall. In addition, drywall screws are often used along with plastic anchors that help distribute the weight of the hung object evenly over the surface.
The pitch of the screw can be classified as either coarse or fine. The more coarsely threaded the screw, the tighter it holds. Plus, since it contains fewer threads, it screws into place faster. On the other hand, although finely threaded screws take longer to insert, they have sharper points, making it easier to insert the screw in the first place. You’re meant to use coarsely threaded drywall screws when you’re attaching the drywall to softwood studs, while finely threaded drywall screws are meant to be used when you’re attaching the drywall to light metal studs.
In addition, specialty drywall screws are designed for specific purposes. For example, when you install drywall onto heavy metal studs, it’s best to use self-drilling drywall screws, eliminating the need to drill holes in advance. Additionally, there are coated drywall screws that protect against corrosion.
