These small countersunk rings can be used for a wide range of applications including closures for cabinet doors and handbags.

Countersunk neodymium disc magnets can be fastened with a countersunk head screw. They are only 4 mm thick and therefore very discreet for hanging up signs, tools, etc. Especially suitable for cabinetmaking, kitchen installations, booth and store construction, signage technology, etc.

Observe: Neodymium magnets are brittle and can break under excessive application of force. Not all holding surfaces are level, which is why magnets need a little slack. This allows them to optimally align with the ferromagnetic object and extend the highest adhesive force. That is why we recommend fastening these magnets by hand.
