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 neodymium countersunk disc magnets are best for securely attaching magnets on to both magnetic and non-magnetic surfaces including wood, plastic, brass, copper, rubber and aluminum.
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.
Neodymium magnets are perfect for use in dry indoor areas.
