We know that the self-tapping screw is a hole that does not need to be tapped. Unlike the mechanical screw, when the mechanical screw is used, it is necessary to drill a hole in the product workpiece, and then directly rotate it clockwise, and self-tapping. Because the head of the screw is pointed, the pitch is larger than that of the mechanical screw, and there is some imagination with the chipless tapping. It can be rotated and fixed directly without the tapping. The screw is fastened by its own thread. The principle, the attack-drill-squeeze-pressure step is combined and closely matched.
Therefore, the installation of the self-tapping screws is very simple, and only needs to work together to install and use.
1. Using a manual screwdriver, select the corresponding screwdriver according to the groove shape of the self-tapping screw. Align the position of the screwdriver with the screw groove and align the position where you want to connect the fastening. Press the screw directly and turn the screwdriver in the clockwise direction. Rotate the self-tapping screws little by little into the workpiece until the thread of the entire screw has not been placed in the workpiece.
2. Using power tools, power tools are more convenient and easier to install. They work the same way as manual screwdrivers, but with electric screwdrivers, self-tapping screws can be installed faster and easier.
