Pot magnet with external threaded stud, also called Neodymium cup magnet with male thread, is a type of magnet that features an external threaded hole or stud on its surface. In the various product and life areas, this threaded stud allows for easy and secure attachment to various objects or surfaces using nuts, bolts, or other threaded fasteners.
Male thread for easy mounting
Strong force but compact size
Epoxy or plastic gasket
Widely use industrial applications
Similar to other types of Neodymium round base magnets, the external threaded pot magnet consists of a ferromagnetic casing or pot that houses a Neodymium disc magnet. The steel cup helps to avoid the collision of the Neodymium magnet in use, and to concentrate and direct the magnetic field to a specific face, known as the magnetic pole.
What Structure of Pot Magnet with External Threaded Stud:
The threaded pot magnet is composed of permanent magnet, steel shell and gasket.
1. Magnet: NdFeB, SmCo, Ferrite, Alnico and other materials can be used to make pot magnet. However, Horizon Magnetics focus on the NdFeB magnet pot magnet.
2. Steel shell: It is steel material and the production process has two types: stamping and turning. The price of stamping process is lower while the dimension precision of turning process is higher. The turning process can produce products with more size requirements, especially the products with larger diameter. Turning process can reach higher accuracy than stamping for the same size. Horizon Magnetics supply pot magnets with thread with both options of turning and stamping so as to meet customers’ diverse requirements, better price or better size accuracy.
2. Gasket: Generally it is plastic material. Sometimes it can be epoxy resin. Both options of plastic ring and epoxy resin are available in Horizon Magnetics.
Typical Applications of Pot Magnet with External Threaded Stud:
The threaded Neodymium magnet combines an external thread into the steel cup of the pot magnet, and is excellent for gripping and holding applications like holding signs, tools and fixtures, clamping, fastening, etc.
1. Holding fixtures: In the industrial applications, Neodymium pot magnets with external threaded stud are attached to fixtures, jigs, machinery conveniently and tightly, and then the can be screwed into place to provide secure and reliable holding.
2. Magnetic clamping: Screw the threaded pot magnets in to place to create a powerful magnetic field which can hold objects together, particularly in woodworking, metal fabrication, etc.
3. Magnetic tool attachment: The threaded stud is easy to screw onto handles, holders or brackets of the tools, and then the tools can have magnetic surface to attract metal objects or accessories.

Precast shuttering magnet or formwork magnet is an innovative magnetic shuttering solution for precast concrete formworks! This siderail shuttering magnet makes it convenient, economic and efficient to fix the side forms and openings firmly onto steel tables and beds during the casting and vibration processes. As a China leading shuttering magnet manufacturer & supplier, Horizon Magnetics keep developing and manufacturing various shuttering magnets to help worldwide precast concrete industry solve problems caused by the traditional formwork fastening methods.
Magnets for PMSM (permanent magnet synchronous motors), particularly sintered Neodymium magnets (NdFeB), are integral components that determine the performance, efficiency, and reliability of PMSM motors. Neodymium magnets are essential components in modern electric motors, providing the necessary magnetic fields for efficient and powerful operation.
Samarium Cobalt ring magnet is the cylindrical shaped SmCo magnets with a center hole through the flat surfaces of magnets. The SmCo ring magnets are mainly used in sensors, magnetrons, high performance motors for example dental motors, microwave communication TWT (travelling wave tube), etc.
Neodymium block magnets are usually square and rectangular block shaped, which are the most common shape of Neodymium magnet. Usually we call them rare earth bar magnets, magnetic blocks, Neodymium bar magnets or rectangular Neodymium magnets. The strong block magnets are always used in industrial markets and small blocks may be used as craft magnets.
