Neodymium Pot Magnet Dia 16mm with counterbore hole Rare Earth Cup Magnet (10 Pack)

This neodymium round base magnet is made of a super strong neodymium magnet encased inside a chrome plated steel cup. The neodymium magnet is bonded inside of the cup with adhesives. This design forms a magnetic circuit which triples the holding force to 16 lbs! At the same time, the steel cup also protects the magnet from being damaged when frequently used.

These pot magnets have a drilled cylindrical hole and can be fastened with a regular screw. For applications requiring countersunk screws, we recommend our pot magnets type CSN-32 with drilled countersunk hole. They also have a diameter of 16 mm.

Please note: The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the pot magnet makes direct and full flush contact. Pot magnets already lose much of their adhesive force at a distance of only half a millimetre to the ferromagnetic surface. This characteristic is more pronounced in pot magnets than in other ferrite and neodymium magnets.
