Countersunk Neodymium Shallow Pot Magnet | Fullzen Technology

Short Description:

Countersunk Magnets, also known as Round Base, Round Cup, Cup or RB magnets, are powerful mounting magnets, built with neodymium magnets in a steel cup with a 90° countersunk hole on the working surface to accommodate a standard flat-head screw. The screw head sits flush or slightly below the surface when affixed to your product.

The magnetic holding force is focused on the working surface and is significantly stronger than an individual magnet. The non-working surface is very little or no magnetic force.

Constructed with N35 Neodymium magnets encased in a steel cup, plated with a triple-layer of Nickel-Copper-Nickel (Ni-Cu-Ni) for maximum protection against corrosion & oxidation.

Neodymium cup magnets are used for any application where high-magnetic strength is required. Neodymium countersunk magnets are ideal for lifting, holding & positioning, and mounting applications for indicators, lights, lamps, antennas, inspection equipment, furniture repair, gate latches, closing mechanisms, machinery, vehicles & more.

Fullzen as a China ultra thin magnet factory, our factory can custom neodymium magnets. Neodymium magnets with countersunk holes with high quality very popular in the world.

    Magnet Countersunk

    These Neodymium Shallow Pot Magnets feature a countersunk hole to accommodate screw fixings. They are ideal for applications where magnets are used closing mechanisms, where the screw head must be concealed, such as cabinet doors, drawers, gate latches and door holdings.

    Countersunk Pot Magnets for Shop Fitting Applications

    They are also ideal for other applications such as shop fitting where magnets are used for attaching shelving, signage, lighting systems and window displays. Neodymium is the perfect material for these applications as it gives a high magnetic strength to size ratio, hence a small magnet can be used in applications where space is limited. The countersunk hole in the magnet can accommodate anything from M3 to M5 screw head size depending on the magnet size. The countersunk magnet range is available in a number of sizes,

    Neodymium NdFeb Shallow Pot Magnets with Countersunk Hole usually takes the surface coating with chrome/nickel/zinc/silver/gold/epoxy and the for the body shape sunk in like the regular shape and irregular shape, all these different requests based on clients’ special customized requests in different industrial area .if you needs more please find us which is a famous powerful magnet manufacturer here in Guangdong China.

    We sell all grades of neodymium magnets, custom shapes, sizes, and coatings.

    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 to solve countersunk magnet offset?

    Solving a countersunk magnet offset involves addressing any misalignment or unevenness between the magnet's countersink hole and the screw head, which can lead to an offset appearance. Here's how you can solve countersunk magnet offset issues:

    1. Check for Proper Alignment
    2. Verify Screw Size and Length
    3. Adjust Screw Depth
    4. Select Appropriate Magnet and Screw Sizes
    5. Use Washers
    6. Modify the Hole or Screw
    7. Consult Manufacturer or Supplier
    8. Test and Adjust

    How to gauge countersunk magnets thickness?

    Gauging the thickness of a countersunk magnet involves measuring the distance from one flat side of the magnet to the other flat side, taking into account the depth of the countersink hole. Here's how to gauge the thickness of countersunk magnets:

    1. Choose a Measuring Tool
    2. Position the Magnet
    3. Measure the Thickness
    4. Read the Measurement
    5. Record the Measurement
    6. Consider the Countersink Hole
    7. Compare with Specifications
    How to develop countersunk magnets yield?

     Here's how you can work on developing countersunk magnets yield:

    1. Quality Control and Inspection
    2. Supplier Selection
    3. Process Optimization
    4. Employee Training
    5. Equipment Maintenance
