How Do Self-Drilling Screws Differ From Self-Tapping Screws?
The most widely used screw kinds are self-tapping and self-drilling screws from Haiyan Gete company. Despite their apparent similarities, they differ in a few significant ways that distinguish their functions and purposes.
Typically used on thin metal sheets or other materials like wood or plastic, self-drilling screws feature a sharp head. They avoid the need for extra tools or drilling bits and save time and work by drilling their own hole.
Conversely, self-tapping screws are better suited for thicker materials or situations requiring precise fits,such as wood, plastic, and some metals, can frequently be used with self-tapping screws.
Why do self-drilling and self-tapping screws not have a slotted wrenching structure?
This is because self-drilling and self-tapping screws require drilling. In order to ensure high-speed installation of electric installation tools, the wrenching structure of self-drilling and self-tapping screws must be able to withstand large impact forces. The separate slotted
wrenching structure positioning points and The force area is small, and it is easy for tools to slip or screws to be damaged during high-speed installation, which is both unsafe and affects assembly efficiency.
