40x10x4mm N35 Neodymium Rare Earth Double Countersunk Block Magnets with Countersunk Hole for #4 Śruba
$16.95
These block countersunk magnets are sold by the pair. One will have the north pole on the side with the large end of the hole and one will have the south pole on that side, so this allows you to pair them together to create magnetic latches, fasteners, and other closure mechanisms. Both the north and south poles will be attracted and attach to anything metal.

These countersunk block magnets 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.
