Ferrite pot magnets with internal thread
Our ferrite pot magnets with internal thread consist of a ring magnet made of hard ferrite, which is installed in a steel pot. In this steel pot, there is an internal thread in the center, which guarantees a quick screw connection with the environment.
The flat design is a major advantage of this flat gripper, which is why it is perfect for applications where space is limited. In addition, they can easily withstand temperatures up to max. 200°C.

Ferrite magnet with internal thread – design and function
The ferrite magnet with internal thread is a combination of a ring magnet made of hard ferrite and a steel pot. The raw magnet is inserted into the steel pot and the edges are filled with epoxy, for example. You could say that the steel pot sits like a pot over the magnet – this is where the term pot magnet comes from.
Due to the flat design and the “gripping” function through magnetism, these magnet systems are also called flat grippers.
Ferrite flat grippers with internal thread have the special feature that the steel cup is threaded in the center. Since this thread is integrated into the magnet itself, it guarantees a very flat design even after assembly. That is why magnet systems with internal threads are perfect for tight installation conditions. Since the basic structure is the same, they have the same advantages as other pot magnets:
- The raw magnet made of hard ferrite is shielded and protected by the steel pot. This makes it more robust.
- The field lines of the magnet are directed through the steel casing to the open holding surface, which increases the holding power.
- The steel casing allows the otherwise fragile magnets to be equipped with various threads. This opens up a wide range of possible applications.
Ferrite pot magnets with internal thread in use
One of the biggest advantages of flat pot magnets is their extreme versatility. Whether at the point of sale, in construction or in mechanical engineering – ferrite pot magnets with internal thread can be used anywhere. They are quickly mounted, last practically forever when handled correctly and are therefore reusable. They are used as holding magnets to magnetically hold counterparts. Screwed onto tool walls, they serve as tool holders. When attached to the back of advertising signs, they become magnetic and adhere to various surfaces on their own.
Caution when using outdoors:
Ferrite magnets are generally resistant to weather and do not oxidize. The steel pot is galvanized and therefore also resistant to rust.
With prolonged use in outdoor areas and regular use, it may happen that the galvanizing flakes off in some places. At these points, rust can occur.
Small amounts of rust are not problematic and affect the magnet only minimally. However, with large-scale oxidation, the ferrite pot magnet with internal thread should be replaced.
