The magnetic assembly that a disc shape magnet with a countersunk hole housed with a flat steel cup is known as flat countersunk cup magnets or countersunk pot magnets, which are used as holding magnets and mounting magnets.
Rare earth neodymium magnets have high magnetic energy and are always used to make mounting/holding magnets for heavy-duty applications. Thanks to the steel cups, as a new type of countersank magnets with steel cups housed outside, the finished magnetic system has several times the magnetic holding force of the naked neodymium magnets.
The working surfaces of neodymium cup/pot magnets with countersunk holes are north pole, are compact and practical for integrating into your projects or ideas. The central countersunk holes of the neodymium cup (pot) magnets are designed for screw, with the counterbore/countersunk mounting holes, our china neodymium pot magnet can be screwed on anywhere for holding applications.
