Product introduction of drywall screw

1. Product overview

Drywall screw, as a very commonly used fastening connector in the field of building decoration, are mainly used to fix various lightweight plates such as gypsum board, fiber cement board on wooden keel, light steel keel or other base structures. Its design is designed to meet the needs of efficient and reliable fastening during the installation of lightweight wall materials, and is one of the important materials to achieve a firm and beautiful wall decoration effect.

2. Product classification

1) According to the shape of the head

• Countersunk head drywall screw: The head is tapered, and the nail head can be completely sunk below the surface of the board after installation, so that the surface of the board is flat, suitable for wall decoration that requires high surface flatness, such as the installation of gypsum board on indoor walls, which can provide a good foundation for subsequent wall decoration (such as scraping putty and painting).
• Round head drywall screw: The head is round, compared with countersunk head nails, the nail head is exposed to the surface of the board, which has a certain decorative property. It is often used in some places where there are special requirements for aesthetics and no need to completely hide the nail head, such as the ceiling decoration of some commercial spaces. The embellishment of round head nails can create a unique visual effect.
• Horn head drywall screws: The head is larger and in the shape of a horn. This design can provide a larger contact area and fastening force. It is suitable for fixing heavier plates or for use in parts that require higher connection strength. For example, in the wall construction of industrial plants, it is used to fix fiber cement boards to ensure a stable connection between the plates and the keel.

2) Classified by thread type

• Single thick thread drywall screw: The thread spacing is larger, the tooth shape is deeper, it can quickly cut into the plate and provide strong anchoring force. It is suitable for the connection of general thickness gypsum board and wooden keel. The installation speed is fast and the construction efficiency is high.
• Double fine tooth thread drywall screw: With two sets of fine tooth thread, this design enhances the friction and biting force between the nail and the plate, especially for the connection between the light metal keel and the gypsum board, which can effectively prevent the nail from loosening and improve the stability of the connection.
• Self-drilling and self-tapping drywall screw: The front end of the nail has the shape of a drill bit, which can be directly drilled into the metal or wood keel without pre-punching, and at the same time tapping out the thread for fastening. At the construction site, it can greatly save the construction time and process, and is often used for the quick installation of light steel keel structure.

3. Product advantages

• Efficient installation: The special design of the drywall screw makes it possible to install quickly and conveniently. Whether it is matched with wood or light steel keel, it can be quickly fastened by ordinary electric screwdriver or pneumatic tool, which greatly improves the construction efficiency and shortens the project cycle.
• Firm connection: Its thread design and nail body material ensure that a firm connection is formed between the light plate and the keel, which can withstand certain tensile and shear forces, and ensure the stability of the wall structure. It is not easy to loose or fall off even during long-term use.
• Anti-rust performance: Most drywall screw are galvanized or other anti-rust treatment processes, which effectively improve the anti-rust ability of the nails. In humid environments or during long-term use, it can prevent the connection strength caused by rust and prolong the service life of the wall structure.
• Wide applicability: It is suitable for a variety of lightweight wall materials and different types of keels. It can play a good fastening role in indoor walls, ceilings in home decoration, and lightweight partition wall construction in large-scale engineering projects such as commercial buildings and industrial plants.

4. Application Scenarios

1) Home Decoration

• Interior Wall Decoration: When installing gypsum board on the walls of living rooms, bedrooms, kitchens, etc., drywall screw are used to fix the gypsum board on the wooden keel or light steel keel, laying the foundation for the subsequent wall decoration process.
• Ceiling Installation: All kinds of ceiling materials such as gypsum board ceiling, PVC gusset ceiling, etc., drywall screws are the key tools to realize the connection between the ceiling and ceiling keel, ensuring the stability and aesthetics of the ceiling.

2) Commercial Buildings

• Office Decoration: In the partition wall and ceiling decoration of office space, drywall screw are widely used to meet the needs of rapid construction and high-quality decoration, while ensuring the safety and comfort of the office environment.
• Shopping malls and shop decoration: Shop decoration inside shopping malls, including the installation of wall display racks, the construction of lightweight partition walls, etc. Drywall screw help to create a diverse commercial space with their efficient and firm characteristics.

3) Industrial buildings

• Plant lightweight partition wall construction: In industrial plants, in order to divide different production areas or set up auxiliary spaces such as offices, lightweight partition walls are often used. Drywall nails are used to fix lightweight plates on the keel to build a strong and durable partition wall structure.
• Warehouse ceiling installation: The ceiling installation of warehouses needs to bear a certain weight and ensure long-term stability. The firm connection performance of drywall nails makes it an ideal choice for warehouse ceiling construction.
