When using self-tapping screws, they do not need to be tapped and can be directly screwed into the connected body. They are commonly used on non-metallic (wooden boards, wall panels, plastic, etc.) or thin metal plates.
It has the following advantages:
1. Easy installation, drilling, tapping, fixing, and locking can be completed in one go. Generally, an electric screwdriver is used to drill holes and then screw them in.
2. No need to use with nuts, saving costs.
3. Corrosion resistance. Self tapping screws are commonly used in outdoor environments, which requires them to have strong corrosion resistance.
4. High surface hardness and good core toughness.
5. Its penetration capacity generally does not exceed 6mm, and the maximum does not exceed 12mm. It is suitable for fixing thin plates, such as the connection between color steel plates in steel structures, the connection between wall beams, and the connection between color steel plates and purlins.
