What stud pot magnet sizes
are available?

Diameter and depth of stud pot magnet Stud pot magnets are always measured diameter x depth. The size always includes the shell within the measurements.


Diameter of stud pot magnet 10mm and 125mm The diameter refers to the distance between the two widest points of the stud pot magnet. It ranges from 10mm (0.39″) to 125mm (4.9″).
Magnetic down light being held by a stud pot magnet The diameter you choose will depend on where the stud pot magnet is going to be used.

For example, if the magnet is going to be used for promotional ceiling signs or light fittings, the diameter should be larger, as the magnet needs greater contact with the ferromagnetic material to provide a secure hold.


Depth of stud pot magnet 5mm and 70mm The depth of a stud pot magnet is the distance from the top of the stud to the magnetic face, and can range from 5mm (0.2″) to 70mm (2.8″).
Depth of wood The depth you choose will depend on the amount of space available for the stud pot magnet. If there is a limited height available, then a magnet with a depth of less than 20mm (0.79″) would be ideal.

Magnetic pull

Magnetic pull of stud pot magnet 0.8kg and 164kg The magnetic pull of stud pot magnets ranges from 0.8kg (1.8lbs) to 164kg (361.56lbs).
Neodymium magnet elements: Neodymium Nd, Iron Fe, and Boron B The magnetic pull is the maximum weight of ferromagnetic material the stud pot magnet can hold. This is not determined by its overall size, but the material the magnet is made from. This means that a large magnet does not necessarily have a larger magnetic pull than a small magnet.

Diameter and depth of stud pot magnet To summarise, when purchasing a stud pot magnet, the key thing to look out for is the depth and diameter. These affect the tool’s ability to hold non-ferromagnetic material to a ferromagnetic surface (e.g. a down light to a steel ceiling).
