Product Description
The China threaded neodymium magnets stud can work like a bolt together with a nut for fastening & holding. In our product the threaded stud and the steel pot are a complete part made by lathe machining and, by producing it this way, it gives superior sturdiness.

The pot magnet with external thread stud is made of rare earth Neodymium(NdFeB) magnet and a round steel or cup plate, which means that the pot magnet has a stronger adhesive force than conventional magnet without steel plate. Due to the external thread stud, these pot magnets can work like a bolt, you can put the stud into a hole and fasten it together with a nut for holding.

Features, at least:
Superior sturdiness: In our product the threaded stud and the steel pot are a complete part made by lathe machining and, by producing it this way, it's much more sturdy than that way of riveting the stud, won’t loose and not easy to rust after a long time use.

Powerful force: By means of a pot steel plate to change the magnetic circuit, the magnetic energy is mostly concentrated on the edge of the metal pot to create strong holding force on this side.

Customized service: We have a professional engineer team who can provide a cost-effective solution to your specific demand, for example the size or the holding force can be customized
Main Test method: Vernier calipers to test the dimensions. Salt spray test for the coating evaluation. Pull tester to measure the vertical pull force and slipping force.

Product application: The round magnet with hole is very popular for indoor or outdoor solutions, such as magnetic camera mount , lighting fixing, tool and cable management etc.
