We know that the self-tapping screws is a hole that does not need to be tapped. Unlike the mechanical screws, when the mechanical screws 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 screws is pointed, the pitch is larger than that of the mechanical screws, and there is some imagination with the chipless tapping. It can be rotated and fixed directly without the tapping. The screws 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 screwsdriver, select the corresponding screwsdriver according to the groove shape of the self-tapping screws. Align the position of the screwsdriver with the screws groove and align the position where you want to connect the fastening. Press the screws directly and turn the screwsdriver in the clockwise direction. Rotate the self-tapping screws little by little into the workpiece until the thread of the entire screws 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 screwsdrivers, but with electric screwsdrivers, self-tapping screws can be installed faster and easier.
