Holding Pot Magnet with Internal Threaded
A HSMAG magnets is sole provider of pot magnets that are internally threaded stud popularly known as Internal Threaded Stud. These magnets have a very large force, which can clamp down the ferromagnetic material because of its Ni or Zinc plated mild steel. Thus, allow a magnetic circuit with improved material, which can achieved with minimal sizes.
Pot Magnets with internal thread stud/Boss mounting have that thick steel backing with female thread section. With help of threads like M4 and M10 screw and a bolt, these magnets have a platform, which can hold the pot magnets with much efficient internal thread with Stud/Boss mounting on the place.

Steel shell on a pot magnet
The steel shell is a casing for the magnet and protects it from any chipping or cracking from contact with a hard surface, and any demagnetising effects. (see Magnets glossary).
The steel pot provides strength for the magnet, which would otherwise be very brittle, and allows threaded holes and studs to be inserted.
The steel shell helps the magnetic field become up to thirty two times stronger than other magnets by concentrating it to only one magnetic face. This means it can hold large objects such as supermarket signs from a ceiling without any additional support.
