Why is the ring countersunk magnet made of countersunk hole?

The circular magnets we often see are all sheet-like circular magnets. This is the ring countersunk magnet. We are very curious whether the magnet can be fitted with screws? This is OK. Why do you say that?

Why is the ring countersunk magnet made of countersunk hole?

We make the inner ring of this magnet into a counterbore, and the shape of the counterbore is actually made like a funnel. Why do you want to be like a funnel? Because the funnel shape is more beautiful than the vertical hole in aesthetic angle, the plane will not protrude after the screw is installed. It is designed in such a way that the protection is very strong and the magnet will not be damaged so easily. From the aesthetic point of view, it is in line with the user’s vision, and from the safety point of view, it can kill two birds with one stone.
