The Flat Head Cement Board Screws combine countersunk design, scraping function, ear structure, and drill tail characteristics, each designed to solve specific connection problems in specific scenarios. The main body is made of high-strength alloy steel material, which undergoes precise heat treatment and surface treatment processes to ensure the high strength, corrosion resistance, and good thread bite force of the screws.
Compared with traditional flat or round heads, the countersunk design can perfectly embed into the material surface, reduce protruding parts, not only beautiful, but also effectively prevent scratches or collisions caused by screw heads, especially suitable for occasions that require a flat appearance. The threaded part of the screw adopts a special scraping design, which can automatically clean the hole wall, remove impurities, ensure the connection between the screw and the substrate, and reduce the risk of loosening during installation.
The unique ear clamp design increases the locking force of the screw in the material, and can maintain a stable connection state even in environments with significant vibration or load changes, reducing the risk of loosening. The tail part of the drill integrates self drilling function, which can directly penetrate thin sheet materials such as metal plates, wooden boards, etc. without pre drilling, greatly improving construction efficiency, reducing tool requirements, and lowering costs.
