Metal discs with an edge and countersunk hole M3

These metal discs with an edge are the perfect magnetic bases for our (e.g.) pot magnets or magnetic hooks. They are countersunk and can be fastened with a fitting countersunk screw to create an even support area.

The edge of these metal discs prevents the magnet from sliding down if attached in a vertical position, which counteracts the shear force and maintains a high adhesive force.

Note: Once a magnet of suitable size (e.g. CSN-20) sits on the disc, it is hard to remove thanks to the edge. Therefore, make sure you first attach the metal disc and the magnet to the desired object (or screw in the hook/grommet/handle).

The metal discs are not rustproof and hence not suitable for outdoor use.
