Countersunk Neodymium Pot Magnets

This neodymium magnetic base is provided with a through countersunk hole to ensure its fixation.


Countersunk Neodymium Pot Magnets are created from a neodymium magnet, so it has a large attractive force, the north pole is located at the core of the magnetic side, and the south at the surrounding end.

Countersunk Neodymium Pot Magnets are a useful tool in a wide variety of applications. These magnetic bases are made up of a high-strength neodymium magnet, covered by a stainless steel or nickel-plated material. The shape of the base is generally round or square, with a thread in the center that is used to hold various objects.

The holding power of these magnetic bases is impressive, making them ideal for applications that require a secure and stable hold. Countersunk Neodymium Pot Magnets can support large weights, up to several tens of kilograms, depending on their size and shape.

Common applications for these magnetic bases include attaching panels, holding tools on workbenches, holding sensors and cameras on measuring equipment, holding lights and lighting fixtures on ceilings or walls, and fixing signs and posters on metal surfaces.

Another advantage of Countersunk Neodymium Pot Magnets is their ease of use. No additional tools are needed to attach them to metal surfaces, making them ideal for applications where quick and easy mounting is needed. Additionally, these magnetic bases cause no damage to the surfaces they stick to as they require no drilling or screws.

It is important to keep in mind that, due to the high magnetic resistance of these bases, they may present some difficulties when removing them from the surface on which they are fixed. Therefore, caution is necessary when removing them to avoid damaging the surface or the subject-object.

Round cup magnets are created from a powerful disc magnet which has a stainless steel hole, at the north pole is the magnetic part.

Standard Measurements:

The data reflected in the table for each type of magnetic base shows us the force values on a 10mm sheet.

Due to its countersunk hole, this type of neodymium magnet allows us to screw into a surface, whether on the ceiling or wall, as well as allowing us to easily fix different types of elements. As well as joining various structures, these types of neodymium magnets are mainly used in the construction and lighting sectors. Upon request, they can be supplied in any other dimension.

Maximum working temperature:

As all neodymium bases are resistant to a temperature of 80ºC, if more is needed, neodymium pieces can be supplied, under the consumer's needs up to 350ºC.
