Ss Metal Piercing Zinc Plated Drywall Screws Nickel White / Black Phosphate 6 - 10 Inch
1. Descriptions:
We are factory to produce many kinds of screws for more than 15 years, every month we can ship 15-20 containers to the world market....
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.
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.

4. Installation:
One of the questions that gets asked a lot around here about installing drywall is what size drywall screws should I use. The Answer: What size screws to use will depend on the thickness and material of the studs you are attaching to.
For hanging 3/8 or 5/8 inch thick sheet on wood studs or joists, then 1 1/4-inch #6 coarse-thread drywall screws are a good choice.
For installing 3/8, 1/2 or 5/8 inch drywall on steel framing runners, channels or studs, then use 1 inch long #6 drywall screws. This applies to single layers of drywall. If you are installing drywall in laminated double-layer construction, additional length screws are required.
