Countersunk Disc Magnets – Strong, Reliable, and Easy to Mount

Disc magnets are among the most widely used magnet shapes. When designed with a central hole and countersink, they become highly practical mounting solutions. These magnets can be screwed securely onto surfaces without losing their magnetic power, making them perfect for both industrial and everyday use.

How Countersunk Magnets Work

A countersunk disc magnet contains a strong neodymium core with a precisely drilled hole. The countersink allows a flat-head screw to sit flush with the surface of the magnet. This results in:

• Firm, permanent mounting
• A clean, professional appearance
• No slipping or damage during use

Most models are coated with Nickel-Copper-Nickel (NiCuNi) plating, offering excellent durability and corrosion resistance.

Sizes and Variants

Countersunk disc magnets are available in a wide range of dimensions, typically from 10 mm up to 40+ mm in diameter. Hole sizes are designed to fit common screw standards:

• M3 screws for small magnets
• M4–M5 screws for medium sizes
• M6 screws for larger, heavy-duty magnets

This makes it easy to select the right combination for any project.

Where to Use Countersunk Magnets

Their versatility makes them suitable for countless applications, such as:

• Furniture making – hidden closures for cabinet doors or panels
• Exhibition and shopfitting – quick assembly and disassembly of displays
• Workshops and garages – tool holders, mounts, and storage solutions
• Advertising and signage – mounting boards, signs, or banners
• Everyday projects – anywhere you need a strong yet discreet magnetic fixing

Pole Alignment – A Key Detail

One important factor often overlooked is pole orientation. If you plan to use two countersunk magnets facing each other, they must be paired so that north and south poles align correctly. Otherwise, they will repel instead of attract.

For this reason, it’s best to purchase magnets that are explicitly designed as matching pairs. This ensures seamless operation and prevents frustration during installation.

Advantages of Countersunk Disc Magnets

✔ Easy screw mounting with flush finish
✔ Extremely strong neodymium magnetic force
✔ Wide range of sizes for different screw types
✔ Durable plating for long-term use
✔ Correct north/south pole pairing ensures reliable results

Conclusion

Countersunk disc magnets combine raw magnetic strength with practical usability. Whether in professional carpentry, industrial setups, or simple DIY projects, they provide a clean and secure fixing method. By choosing the right size and ensuring proper north/south alignment, you’ll unlock the full potential of these powerful magnets.
