The primary benefit offered by drywall screws is their countersunk heads. This means that the entire screw lies flush with the surface of the sheet, creating a smooth and even finish. The countersunk head also helps prevent the drywall screw from breaking the paper surface, a common problem with nails.
There are two basic types of drywall screw for installers to choose from. Type “W” units, or wood screws, have wide, coarse threads. They are used for wood framed buildings, where their coarse threading helps them to securely grip the wood. Type “S” screws are designed for use with steel framing members. They have a sharp, notched head that can easily penetrate the steel framing, as well as fine threads that are designed to pass through the steel.
Drywall screws are a type of self-tapping fastener, which means that there is no need to pre-drill holes. These screws almost always have a Phillips head rather than a slotted head, which provides additional control for installers. Instead of a standard drill, installers use a tool known as a drywall dimpler, which has an adjustable nose to install a drywall screw without tearing the paper on each sheet.
A standard drywall screw can be readily identified by its black finish. This black coloring comes from a phosphate mineral coating that is applied to these screws. This coating helps to minimize rusting and corrosion as the screws are exposed to wet joint compound or paint.
When this happens, drive a nail or screw just above or below the one that’s popped out to secure the drywall. You can then either remove or reinsert the popped fastener, depending on the circumstances. Afterward, use joint compound to repair the hole or dimple and cover with tape.
• When working with 1/2-inch drywall, use 1-1/4 or 1-3/8-inch nails
• When working with 5/8-inch drywall, use 1-3/8 or 1-5/8-inch nails
• In most cases, securing drywall will require fewer screws than nails
• Double-nailing panels will help minimize the occurrence of nail pops
• Nails can be used on wooden studs while screws can be used on wood and metal.
Features
Drywall Hammer: In order to achieve a smooth finish on your drywall, you need to drive nails in properly by pounding them in just below the surface without tearing the paper. This can be extremely difficult with a regular hammer. A drywall hammer has a rounded head that allows you to countersink nails with ease without marring the surface of the wall.
Electric Drywall Screw Gun: Just as nails must be properly inserted for drywall to have a smooth, flawless finish, so too must screws be driven in correctly. If you have a big job to do, a cordless electric drywall screw gun will be highly useful. While an electric drill will certainly get the job done, a screw gun has an adjustable nosepiece that regulates depth, allowing for accurate insertion every time. Some are even self-feeding.
Drywall Adhesive: One way to help minimize nail pops and other fastening issues is to use drywall adhesive in conjunction with nails or screws. This sticky substance can be used to glue down the center of the drywall, meaning that nails and screws only need to hold down the edges.
