How To Use Self-drilling Screws

1. Choose the correct electric wrench, and then put the prepared self-drilling screws into the joint of the electric wrench. 

2. Align the tip of the self-drilling screw to the steel plate to be operated, and gently turn on the switch of the electric wrench.

3. Make an angle of 180 degrees up and down. Press down hard until the screw penetrates and is parallel to the steel plate.

4. Remove the head of the electric wrench from the hexagon of the self-drilling screw to complete the work.

When using hexagonal self-drilling screws, if you can first understand the mechanical properties of hexagonal self-drilling screws, you can use the screws better. Different types of hexagonal self-drilling screws have different mechanical properties, resulting in different applications of hexagonal self-drilling screws. Self-drilling screws can be used directly on the material. It can allow basic materials to be drilled, tapped, and locked, which can save construction time to a great extent. It has higher maintenance and toughness than ordinary screws, and it does not need to be drilled, and the operation can be completed by tapping directly. It is generally used to fix on steel structures, and can also be used to fix on some simple buildings.
