This product is a round ferrite magnet with countersunk screw holes. The reason why the countersunk holes are made is because the funnel-shaped shape is more beautiful than vertical holes in terms of aesthetics, and the plane will not protrude after the screws are installed. Secondly, it is designed so that it is very protective and will not cause the magnets to be damaged so easily. From the aesthetic point of view, it not only meets the user's vision, but also meets the user's use from the safety point of view.
Ferrites with countersunk holes, although not as magnetic as neodymium screwhole magnets, are much cheaper, and not easy to rust, high temperature resistant, and can be used with iron cases.
If you have a need for round countersunk magnets, the quality assurance and beautiful price of courage magnet manufacturers in China, welcome to consult us.
