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.
Strong countersunk ring magnets sized for flat-head screws. The south pole is on the side of the magnet with the large hole, where the head of the screw would be.
These countersunk rings can be used for a wide range of applications including door closures and tool hangers.
Please note: 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.
