Sold in Matched Pairs
Each set of pot/mounting magnets includes 3pcs with the countersunk hole on the north pole, and 3pcs with the countersunk hole on the south pole. This allows you to pair them together to create magnetic latches, fasteners, and other closure mechanisms. Both the north and south poles will be attracted and attach to ferromagnetic materials.

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

Produced in an ISO 9001 Facility
Manufactured to Meet RoHS & REACH Standards


The Benefits of Pot Magnets

Pot magnets, also known as cup or mounting magnets, are standard neodymium magnets that are encased in a protective steel housing on the N or S side. Engineered to provide superior sturdiness and impact resistance, this steel housing or “pot” is also ferromagnetic, thereby incrementally increasing the pull force of the magnet itself.

So, in addition to being exceptionally tough and resilient, neodymium pot magnets also provide a stronger pull force than a regular magnet with an equal N-rating and size. This is because the metal housing focuses the magnetic field in one direction, increasing the magnet's holding power.

Pot magnets give you much greater durability and pull force than regular neodymium magnets, and as a result, you get more magnet for your money.
