Excellent value

Compared to local hardware stores, the price here is much better for this grade of magnet. The finish is smooth and shiny. Will buy again for future workshop needs.

Fast shipping and well packaged

Arrived quickly and were separated by foam spacers so they didn't snap together and break during transit. Very professional packaging for such strong magnets.

Perfect for my robotics project

I needed precise dimensions for a custom robot joint, and these fit perfectly. The 6mm hole aligns well with standard M5 screws. Highly recommend for engineering prototypes.

Good quality, careful with plating

The magnetic strength is exactly as described for N48 grade. Just be careful when screwing them in; if you overtighten, you might chip the nickel coating. Otherwise, great product.

Strong but brittle

One of the magnets cracked when I accidentally dropped it on the concrete floor. I know neodymium is brittle, but just a heads up to handle with care. The remaining ones work great.

Incredibly strong for the size

These magnets are surprisingly powerful. I used them to mount a small sensor housing under a metal shelf, and they hold it securely without any slip. The countersunk hole makes installation very clean.

5 FAQ

Q: Is the hole threaded or smooth?

A: The hole is a smooth countersink, not threaded. You will need to use a screw that passes through the magnet into the material you are attaching it to.

Q: What size screw fits best in the countersunk hole?

A: The 6mm countersunk hole is designed to accommodate an M5 screw head comfortably, allowing for a flush mount surface.

Q: Can these magnets be used outdoors?

A: While the Ni-Cu-Ni coating offers some corrosion resistance, we recommend sealing or painting them if they will be exposed to rain or high humidity for extended periods.

Q: Are these sold individually or in packs?

A: This listing is for a single unit. However, we offer bulk discounts if you select a higher quantity from the dropdown menu before adding to cart.

Q: Will the magnetic strength degrade over time?

A: No, provided they are not exposed to temperatures above 80°C or subjected to opposing strong magnetic fields, they will retain their magnetism indefinitely.
