Large flat head drill tail screw has a drilled tip, and the tip is named after a twist drill. When assembling,
the screw can drill the center hole by itself,and then use the threaded part to tap into the hole on the
carrier to match it. So the thread is called self-drilling and self-tapping screw. Compared with ordinary
screws, its toughness and holding force are higher, and it will not loosen after a long time after combination,
so it is safe to use.
