What is a stud pot magnet?

Internal threaded stud pot magnet and an external threaded stud pot magnet

A stud pot magnet has a stud (cylinder of stainless steel) protruding from the top of its steel shell.

Magnetic down light being held by a stud pot magnet

Stud pot magnets can be used as antenna mounts on car roofs, or to hang promotional signs from the ceiling of supermarkets, or to be the light fitting for a magnetic down light.

Types of stud: threaded, internal threaded, and plain

There are three types of stud pot magnet: internal threaded studs, external threaded studs, and plain studs.

Internal threaded stud pot magnet

Internal threaded studs

An internal threaded stud is a plain stud with an internal threaded centre. The added thread length inside the stud allows a more secure hold with a threaded bolt than without the stud, as on an internal threaded pot magnet.

M4 and M20 diameter bolt and hook screw

The internal threaded hole allows the pot magnet to be attached to non-ferromagnetic materials which have corresponding grooves such as threaded bars, bolts, or hooks. The internal threaded hole can fit M4 to M20 threaded hooks and bolts.

Internal threaded stud pot magnet with attached hook

Internal threaded stud pot magnets can come with a hook attachment.


When a hook is attached to an internal threaded stud pot magnet, the two are known as a ceiling magnet. This is often used to hang promotional signs to supermarket ceilings.

Internal threaded stud pot magnets are also known as female threaded pot magnets. They can attach themselves to external threaded stud pot magnets, which are also known as male threaded pot magnets. This is particularly useful for storage as it allows the two pot magnets to be stored together without one demagnetising the other (see Magnets glossary).

Threads on an external stud pot magnet

External threaded studs

External threaded studs have continuous grooves, known as threads, in a spiral pattern around the outside. They can either be screwed into a threaded hole or placed through a plain hole and then held in place with a nut.

Plain stud pot magnet

Plain studs

A plain stud is a stud without any threads or markings. As it has no threads, the plain stud is riveted to non-ferromagnetic materials.

Riveting the stud on a plain stud pot magnet

"Riveting" is achieved by punching the stud into the material with a rivet gun. This causes the top of the stud to bend into an umbrella shape, holding the stud pot magnet in place.
