Difference between countersunk screws and flat screws
The head of the flat head screw is in a protruding state, and the head of the entire flat head screw is exposed, and it feels strange to the touch. After the countersunk head screw is installed, we will find that the screw is almost completely cut into the product. The head of the countersunk head screw is flat with the surface of the product, and there is no difference in touch. Many product housing screws use countersunk head screws for fastening, because it feels better and looks more beautiful.
