The ceramic coating on these screws is a thin layer of zirconia or silicon nitride, which is known for its extreme hardness and excellent thermal stability. This coating not only enhances the screw's resistance to corrosion but also provides a non-stick surface that reduces friction during installation. As a result, these screws can be driven into materials more easily and quickly, significantly increasing productivity on construction sites.
