Double Countersunk Head Chipboard Screw: High-performance wood screws for perfect joints

2025 - 05 - 13

We use high-quality steel to manufacture each Double Countersunk Head Chipboard Screw, ensuring its excellent strength and durability. Whether it is used to fix wooden boards, assemble furniture, or repair doors, windows and window frames, the screws can stably withstand the stress and pressure of daily use, ensuring that they are not easy to loosen after long-term use. Its excellent corrosion resistance adapts to various environments and is particularly suitable for use in humid environments.

Double Countersunk Head Chipboard Screwprovides three common groove types including Pozi, Phillips and Torx. Users can choose the most suitable style according to the type of tools at hand or personal usage habits to ensure a smooth installation process and enhance the installation stability of the screws. The Pozi groove design, commonly seen in the European market, is an improved Phillips design with better self-positioning ability and greater driving force. Compared with the traditional Phillips design, the four grooves of the Pozi screw head are spaced farther apart, ensuring that the screwdriver and the screw head fit more closely, avoiding slippage and providing higher torque transmission efficiency. In addition, Pozi screws can reduce wear on driving tools, make operation smoother, and maintain stability in high-intensity applications. Phillips groove is the most widely used screw design in the world, with a signature cross-shaped groove. Its advantage is that it can effectively avoid slipping under high torque, allowing the screw to withstand greater pressure during tightening. The Phillips design also helps to improve the accuracy of automated assembly processes, so it is widely used in various mechanical, electronic and construction industries. Torx groove is a design that has gradually become popular in high-performance and high-torque applications in recent years. Its hexagonal star structure not only increases the contact area with the tool, thereby enhancing the torque transmission efficiency, but also effectively reduces the risk of tool slippage. Torx screws are particularly suitable for use in precision machinery or applications requiring strong torque because they can withstand large rotational forces while avoiding damage to the screw head, providing a longer and more stable connection performance.

The double countersunk head design of the Double Countersunk Head Chipboard Screw allows the head of the screw to partially sink into the wood surface, providing a smooth, non-protruding visual effect. This design not only keeps the surface clean, but also avoids the discomfort caused by the exposed screw head, ensuring the beauty and refinement of the final splicing effect, especially suitable for furniture or decoration work that requires a smooth appearance. In addition to the common double countersunk head, we also provide pan head design, which can be selected with or without notches according to needs. The double countersunk head is one of the most common screw head designs, with a smoother and simpler appearance, suitable for most occasions where countersunk installation is required. Its countersunk head design allows the screw to be completely embedded in the surface of the substrate, forming a neat and smooth appearance without protruding from the surface, thereby avoiding scratches or obstructions to other objects. The double countersunk head design is suitable for furniture, woodworking and applications that require a high degree of surface flatness. It not only improves the appearance, but also reduces the impact on the environment and maintains a good appearance. The pan head design is a more prominent and unique head type. Compared with the double countersunk head, the head of the pan head screw presents a flatter appearance and is larger. Its main advantage is that it can provide a larger contact area, disperse the pressure it bears, and avoid damage to the substrate due to over-tightening.

Slots are small grooves carved into the heads of some screws. This design is to improve the anti-slip performance of the screws and ensure a more secure installation. When the contact surface between the screw and the tool is notched, it can better dock with the screwdriver, increase the grip, avoid slippage, and enhance the stability of the screw during tightening. In some high-intensity applications or installation environments that require a lot of torque, the notched design can effectively reduce the slippage between the screw and the tool, and improve the accuracy and safety of the operation. However, for some common application scenarios, users can choose a design without notches according to their needs, which can reduce the wear on the tool while maintaining the basic installation function and extend the tool life.

The diameter range of Double Countersunk Head Chipboard Screw is from 2.5mm to 6mm, and the length ranges from 9.5mm to 200mm, covering a wide range of application needs and suitable for various assembly projects. And this screw product complies with international standards such as DIN7505A and DIN7505B to ensure the high quality and consistency of the product. Made of stainless steel SS410, A2 and A4, it can provide additional corrosion resistance according to different environmental requirements. For surface coating, we offer Dacromet and Ruspert coatings, which further enhance the durability and corrosion resistance of the screws.
