In these products, our neodymium magnets are sunk in a steel pot and have a centered counterbore. Hence, they can be screwed into the wall or ceiling with an appropriate countersunk screw and you can attach various objects.
Besides countersunk pot magnets made of ferrite and in angular shape, you can also find pot magnets with cylindrical borehole as well as screw-on magnets without pot in our assortment.
Firm bolting with subsurface
Use as holding, mounting or cup magnet
Especially suitable for structural solutions in metal, plant or booth construction as well as in the lighting industry
Due to the embedding in a steel pot, the flux lines are directed downwards to the holding surface, which makes the magnetic force especially strong at direct contact with a counterpart.
With a pot magnet with a counterbore, the countersunk head screw fits flush into the depression. After screwing it into the ceiling or wall you can attach ferromagnetic objects, such as metal plates or lamps, to the magnet and easily remove them if necessary. This has the advantage that you will not see any drilling holes on the outside. Our applications with pot magnets show versatile application possibilities.
Maximum adhesive force: This requires the direct contact with a counterpart (e.g. steel plate). Even a small gap due to thin, painted or rough surfaces reduces it. The indicated adhesive force is a value calculated under perfect conditions. It is measured at a right angle to the holding surface, which might make a stronger magnet necessary if you use it on a wall as opposed to a ceiling.
The magnet has to hold a certain weight for your project? Contact us if you need help with this.
Rust: Our countersunk magnets have a nickel coating that somewhat protects them against corrosion. We recommend using them in dry indoor areas or purchasing ferrite pot magnets.
