Internal (female) Threaded Ferrite Cup Magnets

Internal (female) Threaded Ferrite Cup Magnets

A disc ferrite magnet covered with a shallow steel cup with an internal or female threaded stud is known as internal&female threaded ferrite cup magnet.Internal thread ferrite cup magnets are used magnetic bases for ferrite magnetic hooks.

The internal(female) threaded ferrite pot magnets are assembled with disc magnet and steel shell/cup.On top of the steel shell, the is a internal threaded bushing.The steel pot not only keep the magnet safe from damages but also make the magnetic force higher! Because of the steel shell, there is only one magnetic surface that used for working, the optimal surface is steel and iron.Thanks to the internal threaded bushing,steel hook and eyelet can be screwed on the internal threaded ferrite pot magnets.

All the ferrite pot magnets with internal threaded socket are made of anisotropic ferrite magnets. Our ferrite cup magnets maybe even stronger! The steel pot/cup can be made with chrome plated, nickel plated, zinc coated and paint coated, even rubber coated.The below table shows the standard models of internal threaded ferrite pot magnets.

Such internal threaded ferrite pot magnets can be used as magnetic hooks for holding
Such internal threaded ferrite pot magnets can be used as magnetic bases for mounting.
The large internal threaded ferrite pot magnets can be used for magnet fishing.

The large internal threaded ferrite cup magnets make it possible to hold heavy objects to any metal surface. The strong and permanent magnetic force will not lose even used several years. The standard sizes of our ferrite cup (pot) magnets  with female(internal) threaded bushing are available in diameter from 10mm to 125mm, and magnetic holding force is up to 130kgs. If no standard female threaded ferrite cup magnets can be used for you,then try our neodymium internal threaded pot magnets.

The magnetic pull force was measured on a 10 mm thick polished steel plate at room temperature. In special cases, the maximum deviation may be - 10%. Generally, it usually exceeds the value. Small scratches and breakage in the magnetic material do not affect the pull force of the whole ferrite cup magnet. Depending on the type of application (installation, temperature, thickness of the object being sucked), the pull force is greatly affected. The tension value is only for reference, not as a standard to measure the quality of the ferrite pot magnets.
In addition to standard sizes, we also offer custom solutions for internal ferrite pot magnets.
