First fix the self-tapping screw sleeve on the matching screw, fix it with the same type of nut, then use a wrench tool to screw the screw sleeve into the bottom hole, and then withdraw the screw.
2. If the total number of installations is large, it is recommended to use special threaded insert installation tools, such as a hexagon head, a tapping wrench tool, and a pneumatic wrench.
