Countersunk Nodymium Magnets – NdFeB Magnets Factory | Fullzen

Short Description:

Countersunk circular neodymium magnets are a unique type of magnet. Disc or block magnets have counterbore holes to fit screw heads perfectly. Magnets with countersunk mounting holes hold screws in place and flush with the screw heads, making them ideal for any installation job.

The neodymium disc countersunk magnet is plated with three layers of nickel, copper, and nickel, which can reduce corrosion, provide smoothness, and greatly increase the service life of the countersunk magnet.

Countersunk hole magnets are 0.31 inches diameter x 0.12 inches thick with a 0.12 inches diameter countersunk hole, which allows them to be fixed to non-magnetic surfaces with a screw. Please note that the main picture is for display only, the actual size is subject to the attached picture. Or contact us for customized services.

The application of a strong magnet with a hole is greatly expanded. Tolerances: ±0.2mm (±0.008 inch). Our factory, Fullzen Technology, has quality assurance; all magnets are made under ISO 9001 Quality Systems.

    Strong Neodymium Countersunk Magnets Custom

    The circular rare-earth magnet can directly absorb magnetic materials and be fixed on non-magnetic materials with screws. Neodymium magnets with holes are strong and reliable. Be careful and slide gently when detaching the counterbore magnet.

    Strong neodymium disc magnets with holes can be applied to tool storage, photo display, and refrigerator magnets. They can also be used for science experiments, locker suction, or whiteboard magnets.

    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.


    Countersunk magnets what PE is stronger?

    In the context of countersunk magnets, "PE" is not a common term or acronym used to describe magnet properties or characteristics. It's possible that there might be a misunderstanding or miscommunication regarding the terminology.

    When discussing the strength of countersunk magnets, the factors that primarily affect their strength include the magnet material, size, grade, and the specific application conditions. The strength of a magnet is usually measured in terms of its magnetic field strength, which is often indicated by the magnet's maximum energy product (BHmax) or its pull force.

    If you're referring to a specific parameter or term related to countersunk magnets and their strength, I'd be happy to help if you provide more context or clarification. Otherwise, if you're looking for information about the strength of countersunk magnets, it's important to consider the magnet material (e.g., neodymium, ferrite, alnico), grade, and size to determine the appropriate magnet for your application's requirements.

    What are countersunk neodymium magnets good for?

    Countersunk neodymium magnets are versatile and have a wide range of practical applications due to their strong magnetic properties and convenient countersunk hole design. Here are some common uses and applications for countersunk neodymium magnets:

    1. Cabinet and Furniture Making
    2. Signage and Displays
    3. Industrial Fixtures and Mounting
    4. Point of Sale (POS) Displays
    5. Doors and Latches
    6. Marine and Outdoor Equipment
    7. Automotive Applications
    8. DIY and Craft Projects
    9. Repair and Maintenance
    10. Custom Magnetic Closures

    It's important to select the right size, grade, and quantity of countersunk neodymium magnets for your specific application. Additionally, proper handling and consideration of the magnet's sensitivity to temperature changes are essential to ensure effective and safe use.

    How do countersunk magnets?

    Countersunk magnets are magnets with a specially designed countersunk hole on one or both sides, allowing them to be attached to surfaces using screws while maintaining a flush and neat appearance.

    1. Select the Right Magnets
    2. Prepare the Surface
    3. Determine Polarity
    4. Positioning
    5. Choose the Right Screw
    6. Attach the Magnet 
    7. Tighten the Screw
    8. Testing
    9. Repeat as Needed
    10. Consider Application-Specific Details
    11. Safety Precautions
