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.

Sold in Matched North/South Pairs

Each set of countersunk magnets includes 2pcs with the countersunk hole on the north pole, and 2pcs with the countersunk hole on the south pole. This matched polarity design makes it easy to pair the magnets face-to-face for magnetic latches, closures, fasteners, cabinet doors, displays, fixtures, and other applications where two magnets need to attract each other.

Both north-pole and south-pole countersunk magnets will also attract to ferromagnetic materials such as steel, iron, and other magnetic metals, so they can be mounted to metal surfaces or used together as matching magnet pairs.

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

Torque Information for Countersunk Neodymium Magnets

Countersunk neodymium magnets are strong but brittle, and they can crack or break if screws are overtightened. Unlike steel washers or mounting plates, neodymium magnets do not flex under pressure, so too much screw torque can damage the magnet around the countersunk hole.

For best results, we recommend hand tightening whenever possible. If you use a drill or electric screwdriver, start on the lowest torque setting and slowly increase only as needed. Do not continue tightening once the magnet is securely seated.

Magnet Safety Warning

Please use extreme caution when handling these 32 x 8 mm disc magnets. They are incredibly strong and powerful, and can pose a serious risk to your safety.

These large, grade N42 disc magnets are very difficult to separate and can snap back together with incredible speed and force. This may cause them to break and send small fragments flying into the air, potentially causing injury.

With 90 lbs of pull force, these disc magnets can also severely pinch your fingers if they snap back together. For your safety, keep these strong magnets far apart and at a safe distance of several feet or more once separated. Hand and eye protection is strongly recommended when handling these magnets.
