Neodymium Ring Magnet Ø15 x Ø8.1 x 4 mm N35 NiCuNi with countersunk hole South pole

For a neat installation

You can flush-mount this neodymium ring magnet with a countersunk hole, so it won't protrude from a panel, display, or technical setup. The hole is in the middle, with dimensions of Ø15 x Ø8.1 x 4 mm. Small in form, but with enough grip for applications where you don't want a loose solution.

The finish feels like this

The NdFeB core has an N35 magnetization and is finished with NiCuNi, i.e., nickel-copper-nickel. This gives it that silver-colored, smooth outer layer that you quickly recognize when you hold it. It is well-suited for dry indoor environments, for example, in interior construction, sensors, or furniture.

The one you reach for

If something needs to be securely fastened without a large housing, this type of ring magnet is what you need. The South Pole version makes it handy for fixed setups and thoughtful mounting, yet sharp enough to work with carefully. Keep fingers away; it grabs faster than you think.
