Self-drilling screws require a dedicated electric drill (600W recommended). Select a suitable socket or Phillips head bit and install it on the drill; then connect the screw.

Apply approximately 13 kg of force to the drill by hand; ensure the force is on the same vertical line as the center point; turn on the power switch; do not stop midway; once the screw is in place, stop drilling immediately (to prevent incomplete or excessive drilling).
Different models of self-drilling screws often have different usage methods, so mastering the use of one model means mastering the use of many others.
