Our cap magnets, also known as pot magnets or cup magnets, are designed for industrial holding and mounting applications that require strong, concentrated magnetic force. Available in both neodymium and ceramic options, these industrial cap magnets use a steel cup to direct the magnetic field to a single surface, maximizing holding strength while protecting the magnet from damage.

Frequently Asked Questions

What are cap magnets?

Cap magnets, or pot magnets, are magnets encased in steel cups to create a stronger, focused holding force.

Where are cap magnets used?

Cap magnets, also known as pot or cup magnets are typically used in fixtures, mounting systems, robotics, and prototypes requiring secure but removable attachments.

What types of cap magnets do you carry in stock?

We stock cap magnets in several styles and materials, all available online:

Neodymium (NdFeB) & Ceramic (Ferrite) – Choose between maximum strength or cost-effective holding power.
Threaded & Hook Styles – Male and female threaded options, including hook attachments.
Countersunk Caps – For secure screw mounting.
Plain Caps – Simple cup design for general holding applications.

Can you produce custom sizes, magnetization direction or coatings?

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
