Halogen-free screw

The surface of the screw is fully covered with a layer of cobalt and tungsten carbide composite alloy powder coating, which gives the screw good wear resistance and corrosion resistance. And it is not suitable for denaturation and will never fall off permanently,
Extending the lifespan of the screw is three to four times that of ordinary double alloys. Suitable for adding over 40% fiberglass and halogen-free materials.
