Sold in Matched North/South Pairs

Each set of adhesive block magnets includes 10pcs with the adhesive on the north pole, and 10pcs with adhesive on the south pole. This allows you to pair them together to create magnetic latches, fasteners, and other closures. Both the north and south poles will be attracted and attach to anything metal.

If you need the magnets in a different configuration, please contact us.


Adhesive Usage Instructions and Best Practices

3M VHB adhesive works best on smooth, clean, and non-porous surfaces such as metal, glass, plastics (like acrylic and polycarbonate), painted or powder-coated surfaces, and sealed wood. For optimal adhesion, surfaces should be thoroughly cleaned with isopropyl alcohol.

Due to the incredible strength of neodymium, we strongly recommend allowing 24 to 36 hours for the adhesive to cure.

However, for porous materials like raw wood, concrete, fabric, or unsealed surfaces, traditional glue or liquid adhesives provide a stronger bond, as VHB tape relies on full surface contact to achieve its high-strength hold.

These magnets are perfect!

I needed some drawer catches in frameless cabinets. No place to mount conventional parts. These thin magnets are perfect, and much stronger than expected. I couldn’t be happier!

3m Adhesive

Some of the magnets ripped away from the adhesive and attached themselves to the other magnet when using them for cabinet doors

Worked well.

It would be nice, however, if the magnets came in 2" size as well.

They worked great.

Items in the garage.

Did the trick!

I needed these to augment a knife holder that would not support a new set of chefs knives. It was a little tricky finding the right spots where the original magnet was weakest but once I did they worked great.
