What is the main purpose of the horn head shape design of Carbon Steel Drywall Screw?

The design of the horn head allows the head of the carbon steel drywall screw to form a deeper and wider bite area when screwing into the material, effectively increasing the friction between the screw and the material, thereby greatly improving the fastening effect. This is particularly important for structures that need to withstand certain loads or experience periodic stress, such as ceiling systems, wall fixings, etc.
After experiencing vibration, temperature changes or long-term loads, ordinary screws may gradually loosen due to material expansion and contraction or stress release. The horn head screw, with its excellent bite ability, can effectively resist these external forces and maintain the long-term stability of the connection.
The geometric shape of the horn head makes it easier to guide the screw to the predetermined hole position during installation, especially in the process of automated or semi-automated installation, reducing the number of misalignments and retries and improving work efficiency.
In some areas with small spaces or difficult to directly observe, the design of the horn head screw allows it to be installed smoothly with appropriate tools even if the operating space is limited, enhancing the flexibility and adaptability of the installation process.
Drywall screws are mainly used for lightweight building materials such as gypsum boards and lightweight partition boards. The design of the horn head can effectively disperse the pressure generated during tightening, reduce damage to the surface of the material, and keep the installation surface flat and beautiful. In porous materials such as gypsum boards, the subtle texture of the horn head can better embed the material fibers, enhance the grip between the screw and the material, and ensure a more secure connection.
In occasions where interior decoration effects are pursued, horn head screws are usually designed to be sunken, that is, the screw head is slightly lower than or flush with the surface of the material, and is covered by filling or paint, making it almost invisible, keeping the space neat and beautiful. Specific horn head designs may require special tools to remove, which is important in occasions where unauthorized access or modification needs to be prevented (such as inside electronic equipment, security facilities, etc.).
Although horn head screws usually require a specific hex wrench or special screwdriver head for installation and removal, this design also promotes the standardization and innovation of tools. There are a variety of adapter tools on the market to meet the needs of different scenarios.
