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.

Tracy Myerson: ...purchased N42 Neodymium magnets, they are the real deal...had previously bought magnets on Amazon that were advertised as N52, they were just another cheap Chinese fake....
Ron Bennett: Fantastic support and product. Beats Amazon price with real customer service...product was of the highest quality and exactly as described.
Peter Maran: Their Neodymium magnets are superb in quality and price; ...tools, magnifiers, tweezers, and so on, all quality made...
