Magnetstek Engineering, with over 20 years of industry experience, supplies countersunk magnets with quality rare earth material to ensure a super strong pulling force and long-term durability. We can produce NdFeB and SmCo countersunk magnets according to requests. Feel free to talk to our experts for more information.
Countersunk magnets, also known as countersink magnets, counterbore magnets, are a type of magnet with a countersunk hole or depression on one face. This design allows for easy and secure attachment to surfaces using a screw. Countersunk magnets find various applications in industries where a flush and secure magnetic attachment is needed.
Before customizing your countersunk magnets, there are a few things you need to figure out: material, shape, size, use, and working environment. The size here includes magnet dimensions and countersunk hole size.
Size and Shape: Countersunk magnets can be customized in various sizes and shapes to meet specific application requirements. Disc shape and bar shape are the most used ones.
Magnetizing Direction: One pole(N/S) or two poles(S-N/N-S) on the larger-hole surface.
Coating Options: Consider coatings like nickel, zinc, or epoxy to protect the magnet from corrosion. NiCuNi triple-layer coating is the most used one, which can balance the costs and protection.
NdFeB Magnets: Neodymium Iron Boron magnets are often used for their strong magnetic properties, such as tool organizers
SmCo Magnets: Samarium Cobalt magnets are often used for their strong magnetic properties and high-temperature resistances, suchh as ooperatormicrowave ovens.
Other Magnet Types: AlNiCo or Ferrite magnets may also be used depending on the specific requirements.
Single Countersink: A single countersunk hole on one face of the magnet.
Double Countersink: Countersunk holes on both faces, allowing for versatile mounting options.
Screw Size: The choice of screw size is crucial for proper attachment. It should fit snugly into the countersunk hole.
Surface Preparation: Ensure the surface is clean and flat before attaching countersunk magnets for optimal performance.
MagnetsTek invests heavily in product development annually, distinguishing us from other suppliers in the industry.
