Magnet with Countersunk hole, also called neodymium channel magnets with countersunk holes, countersunk hole powerful magnets, are installed and fixed at the desired position by screws. The size of the countersunk magnet generally uses a large D to represent the diameter, d1 represents the diameter of the countersunk hole, d2 represents the inner diameter of the straight hole, and H represents the thickness (height). Neodymium super magnets are big screws on the children’s toys at home, especially the robot. Although it looks easy to unscrew, but it is difficult to get it in practice. It feels like something is sucking it. This is a round sink hole. A special kind of magnet: the screw hole magnet.
Ring magnet, he is a round magnet, which is hollowed out. The round magnets we often see are all a piece of round shape. However, we are curious, can this magnet be fitted with screws? First of all, we made the inner ring of the magnet into a counterbore, and the shape of the counterbore is actually made like a funnel. Why make it like a funnel? Because the shape of the funnel is more beautiful than the vertical hole in terms of aesthetics, the screw will not cause the plane to protrude after installation. Secondly, it is designed to be particularly protective and will not cause the magnet to be so easily damaged. From the perspective of aesthetics, it conforms to the user's vision and satisfies the user's use from the perspective of safety. This kills two birds with one stone.
In modern society, magnets are widely used. Among them, there are many magnets that we have never seen in applications. There are also many magnets that are also used in our common applications in life. Today, I will introduce a small application of countersunk magnets - closing wooden fences.
Since these magnets have countersunk screw holes in the middle, they can be attached to non-magnetic surfaces and therefore wooden doors. Using the characteristics of magnets, using the principle of same-sex repulsion and opposite-sex attraction, the n-level end is buried in the door, the s-level end is buried in the fence, and then fixed with screws. One thing to note here is that the magnet should be flush with the gate and fence.
When the door is pushed to the closed position, the opposite sex attracts the principle of the magnet, so that the S-pole countersunk magnet will be attracted in the fence together with the N-pole countersunk magnet, and the door will be closed. Because the magnets are installed in the gate and fence, it is safe and beautiful. As you can see, this solution is an easy and quick installation that will keep your door closed. Since this is an outdoor application, our magnet manufacturer recommends that you apply a protective varnish to the magnet to reduce the risk of rain corrosion.

This neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos.
Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.
Countersunk magnets, also known as countersink magnets, are magnets that have a specially designed countersunk hole on one or both sides of the magnet. A countersunk hole is a conical depression that allows a screw to sit flush with the surface when it's screwed into the hole. The purpose of countersunk magnets is to provide a convenient way to attach the magnet to surfaces using screws while ensuring a smooth and flush installation.
Countersunk magnets are used for a variety of applications where secure attachment to surfaces is required while maintaining a neat and flush appearance. The countersunk design allows screws to sit flush with the magnet's surface, enabling convenient installation without protruding hardware. Here are some common uses of countersunk magnets:
Yes, you can rivet a countersunk magnet to a surface, but it might require some special considerations due to the unique design of countersunk magnets. Riveting a magnet involves using a rivet, a cylindrical fastener with a head, to secure the magnet to a surface.
