Pot magnet w. internal thread, Ø25 mm.

These magnets are strong neodymium magnets with M5 internal threads and have a reinforcing steel pot on the exterior.

You can screw this magnet directly because of the internal threads feature.

Diameter: 25 mm.
Height: 7 mm.
Magnetism: N38
Surface: nickel-coated (Ni)
Thread size: M5
Max. temperature: 80°C

This magnet has a strength capability of 14 kg. (30.865 lbs.), which has been measured in direct pull on a thick steel plate: A pure piece of magnetic steel. Pro-Tip: The more distance you have between the magnet and the magnetic surface, the weaker the magnetism level. And in the case of a downward pull, a calculation of the strength requirement will need to be done. This is because a downward pull has a different requirement for the magnet than in the case of a direct pull.

ATTENTION! Pot magnets are not made of stainless steel or have a stainless-steel protective coating, which is why we only recommend they are used indoors. Using pot magnets for an extended period outdoors will result in the magnet rusting and failing.

It is crucial to point out that pot magnets with a steel pot should not be used on glass boards, because the steel pot will easily scratch the glass board surface if you are not extremely careful.
