FAQ about drywall screw
- Definition of drywall screws
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.
- 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 the 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 coarse 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.
- What Is the Difference Between Wood Screws & Drywall Screws?
Hundreds of different types of screws can make figuring out which one to use for a particular job a little overwhelming, but matching the screw to the job is critical for a successful project. Screws are named according to what material they are intended for: Drywall screws are used for fastening sheets of drywall to the wood or metal framing for a building. Wood screws are used for fastening pieces of wood.
- What They Are Made Of?
Wood screws are made of zinc-plated steel, stainless steel, silicon bronze (used mostly in boat-building and restoration), and brass (usually chosen for its decorative appeal). Drywall screws are made of case-hardened steel. They are usually black, due to a black phosphate finish on the steel.
- What are the usual sizes?
Wood screws are numbered from 0 to 20, indicating a diameter from about 1/16 in. to 5/16 in. The length of wood screws is measured in inches and fractions of inches and ranges from approximately 3/4 inches long to 4 inches. Drywall screws are available in sizes 6 to 10, with the size indicating threads/per inch. The length of the drywall screw suitable for a particular job depends on the thickness of the drywall. For hanging 3/8-inch to 5/8-inch thick drywall on wood studs, 1-1/4-inch long, #6 coarse thread drywall screws would work well. For installing 3/8-inch, 1/2-inch, or 5/8-inch thick drywall on steel studs, the drywall screws should be 1 inch long.
- What is the feature of the head?
Wood screws are available with a variety of heads that correspond to the type of driver needed to install them and the use to which the screw is being put. Slotted-head and Phillips-head screws correspond to slotted (straight) and Phillips head screwdrivers. Slotted screws and Phillips head screws come with flat heads, oval heads, and round heads. Flathead screws are countersunk below the surface of the wood, and the hole is filled with a dowel or wood putty. Oval head screws are not countersunk and the oval head gives a more finished look to the project. Roundhead screws protrude above the surface of the wood for a decorative effect. Drywall screws have bugle heads, which are set a little below the surface of the drywall, with the holes filled with joint compound when the drywall is finished. Drywall screws for trim have a flat head that fits a Phillips head screwdriver or a flat head that fits a square driver.
- What is the feature of tip?
Wood screws usually require a pilot hole to get them started, although some wood screws, like all drywall screws, have very hard, sharp tips that make them self-starting, or self-tapping. Self-tapping screws do not require a pilot hole; they are driven directly in the material with a manual screwdriver or electric driver.
