Make your own self-adhesive neodymium magnets with our 2.5x1mm thin Nd disc magnets. With the right adhesive, you can make a small sticky magnet dot with a pull of up to 80 grams on most surfaces. Use them to organize light objects, hang family pictures & photos or even magnetize chess pieces. Get an effective alternative to magnetic tape, stickers and strips.

Prototyping & unsure of which magnet is best? You can buy just 1 or several of our many even stronger thin Nd disk magnets. 

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

We also provide complete Documentation including MSDS & ROHS; see below.

Need more pull power & prefer to use adhesive glue dots, double sided stickers or pre-cut double-sided foam squares? Our 7.5x1mm or 12.5x1mm may be just the right size for you. If intended for industrial use & you require a simple but effective Q/A method, use with our magnaprobe to ensure consistent north & south poles.

Otherwise, using regular hardware store should be straightforward. Your fingers have natural oils than can interfere with bonding so clean all surfaces with rubbing alcohol (isopropanol). Neodymium magnets have a smooth nickel coating so scuff the surface with fine sandpaper. You can use a variety of different glues such as 2 part epoxies, cyanoacrylate (crazy glue) or urethane based adhesives such as Gorilla glue.
