Advantages
【Powerful Holding Force】
By combining high quality sintered NdFeB magnet with a precision-machined steel cup, the magnetic field is concentrated onto the working surface, significantly increasing the pull force compared with a standard magnet of the same dimensions.
【Durable Nickel Coating】
The mounting neodymium countersink magnet features premium triple layers nickel-copper-nickel coating that provides outstanding corrosion resistance, surface hardness, and wear protection.
The smooth metallic finish not only gives the magnet an attractive appearance but also protects the neodymium material from moisture, oxidation, and everyday environmental exposure.
【Wide Range of Applications】
Neodymium pot magnet is widely used in automation equipment, machine fixtures, positioning devices, inspection tools, magnetic holders, display systems, cabinets, woodworking jigs, packaging machinery, robotics, electronic equipment, and customized engineering solutions. It is also an excellent choice for DIY enthusiasts, prototype development, and maintenance projects requiring secure yet removable magnetic fastening.

Frequently Asked Questions
Q1: What is a pot magnet?
A: Heavy duty pot magnet is a neodymium magnet enclosed in a steel cup that concentrates magnetic force, providing stronger holding power and better protection than a standard magnet.
Q2: How do I install this magnet?
A: The magnet has a hole in the center for mounting with a standard screw. It can be fixed to metal, wood, or other robust surfaces, providing a simple and secure installation solution.
Q3: Can it be installed without screws?
A: Yes. For non permanent installations, depending on the application and load requirements, the magnet can also be used in conjunction with strong double-sided adhesive or with other magnets.
Q4: How do I choose the right pot magnet size?
A: Choose the size based on the required holding force, mounting space, load weight, and contact surface. Larger pot magnets generally provide stronger magnetic performance.
Q5: Can the magnet's size, magnetic force, or coating be customized?
A: Yes. Size, magnetic rating, coating type, and installation method can all be customized to your project requirements. Please contact us for detailed specifications.
