Unrivaled N52 Holding Strength
Because manufacturers craft these magnets from N52 grade neodymium—the strongest permanent magnetic material available today—they deliver exceptional magnetic pull force. Although they feature a compact 20mm x 10mm x 4mm profile, their concentrated magnetic field reliably holds heavy components in place. As a result, you can trust them to perform flawlessly even under demanding physical conditions without slipping or shifting.
Precision Engineering & Seamless Mounting
Additionally, our production team manufactures each magnet under strict quality controls to ensure exact dimensions and uniform magnetic alignment. Furthermore, the pre-drilled countersunk hole allows standard flat-head screws to sink completely flush into the magnet’s body. Because the screw head sits level with the surface, you achieve a clean, professional finish on every installation. Consequently, mounting these magnets securely onto wood, metal, masonry, or plastic surfaces becomes fast and simple.
Highly Versatile Applications Across Industries
Thanks to their impressive strength-to-size ratio, these rectangular countersunk magnets adapt seamlessly to a wide range of tasks. For example, you can utilize them across multiple environments:
-
Industrial & Manufacturing: For instance, they work exceptionally well in cabinet catches, machinery jigs, automotive assemblies, and concealed structural panels.
-
Woodworking & Cabinetry: Moreover, craftsmen use them for custom hidden door latches, secret compartment closures, and heavy-duty tool holder racks.
-
DIY Crafts & Workshop Projects: Similarly, hobbyists rely on them for custom displays, 3D printing fixtures, magnetic signage, and workshop organizers.
