Neodymium Magnets Countersunk – Magnet Supplier | Fullzen

Short Description:

Counterbore magnets are very popular among merchants and manufacturers. Frequently used as magnetic closures for cabinets, gates and latches, and any other concealed magnetic closures. Rare earth magnets are brittle and can break easily if mishandled; countersunk magnets provide a convenient way to hold the magnet in place without causing damage. This magnet not only has a round base, but also a square base.

The block magnet is mounted in a steel cover to protect the magnet and enhance the magnetic force. In addition, Ni+Cu+Ni three-layer plating provides anti-rust protection in wet environments. Neodymium magnets with strong retention hold up to 35 lbs (16 kg) vertically and 9 lbs (4 kg) horizontally.  We can custom counterbore magnets with square bottom for you.

The magnetic retention is concentrated on the work surface and is significantly stronger than a single magnet. Non-working surfaces have little or no magnetism. Fullzen is a professional permanent magnet manufacturer,
we have produced many large neodymium countersunk magnets, please contact with us.

    Neodymium Magnets Countersunk-Magnet Chain Manufacturer

    The magnets with countersunk holes can be easily mounted using the screws provided. Please note that the magnets are fragile and do not bump into each other. Countersunk magnets enable non-magnetic materials to adhere to metal surfaces, including plastic, wood, glass, and ceramic surfaces. These strong magnets fit into the holes and are secure with grub screws. Combined with metal strikers, they are ideal closing devices for cabinets, shutters, or doors.

    Magnets are manufactured under ISO 9001 quality system.

    Magnetic Product Description:

    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. 

    Uses For Our Strong Rare Earth Disc Magnets:

    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.


    How do countersunk magnets work?

    Countersunk magnets work by combining the attractive force of the magnet with the functionality of a countersink hole. This design allows the magnet to be attached to surfaces using screws while maintaining a flush and concealed appearance.

    Where can I buy neodymium magnets with countersunk holes?

    Neodymium magnets with countersunk holes are widely available from various suppliers, both online and offline. Here are some options for purchasing neodymium magnets with countersunk holes:

    1. Online Retailers
    2. Specialized Magnet Suppliers
    3. Local Hardware or Craft Stores
    4. Industrial Suppliers
    Countersunk magnets what pole is stronger?

    Both the North (N) and South (S) poles of a countersunk magnet have equal strength in terms of their magnetic properties. In other words, the strength of the magnetic field is the same regardless of whether the N or S pole is facing out.
