Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, however it is a versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the grip diameter.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.
Types of drywall screws:
Drywall screws are classified according to length and pitch. There are two common types of drywall screw lengths: S-type and W-type. S-type screws are designed for attaching drywall onto metal. Their sharp points make penetrating the surface easier. W-type screws, on the other hand, are longer and thinner. They are designed for installing drywall onto wood. Although drywall panels differ in thickness, it’s usually sufficient to drive W-type screws into the wood at least 0.63 inches (1.6 centimeters), and for S-type screws to penetrate a metal stud to a depth of 0.38 inches (0.9 centimeters) If you are screwing through multiple layers, make sure the length of the screw is enough to penetrate at least 0.5 inches (1.3 centimeters) into the second layer.
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.
How to Choose the Right Drywall Screws:
Drywall screws are a little more expensive, but they do provide a stronger hold. There are many drywall fasteners that come in the form of a Philips head, but they are not all the same in terms of performance and value. The screw you choose will largely depend in the drywall application you have in store, but also on the quality of screw you are looking for. Here are four of the most common drywall screws used to hang gypsum:
1.Self-Drilling - Also used as pan head screws, these are effective for metal stud framing.
2.Course - These have course threads that securely fasten drywall to its studs.
3.Fine - These screws have smaller heads and finer threads that work well to secure gypsum board.
4.Trim-Head - Use these screws to attach wood trim over drywall.
