Csk head selfdrilling screws from LITUO Fasteners are highly durable and corrosion-resistant, which allows them to be used in extreme temperatures and undersea applications as well. Since these screws are selfdrilling, they can be used without drilling the pilot hole.

2.Application of Self-drilling screws:
Self-drilling screws have hardened drill points that will drill and thread in structural steel, mild steel, aluminum, and wood.
These drill points are manufactured in the same method as the high-speed drill bits.
Self-drilling screws are available in a variety of finishes with unique product features to suit a wide range of environmental conditions.
1.For the fastening process in steel, they are used on steel frame construction or fastening other materials on steel.
2.For the fastening process in wood, they are used for applications in wood structures or industrial lightweight constructions, such as roof deck, flooring.
3.For the fastening process in aluminum, they are used for special industrial applications, construction, and manufacturing of windows.

3.Installation Steps:
