Product information "Blockmagnet 20.0 x 20.0 x 3.0 mm N45 nickel - M3 countersunk hole"
In the middle of this magnet has a 3.5 mm hole with countersunk for an M3 screw so that you can screw on the magnet.
They cannot be used in pairs, as the north pole is always on the depression side and the magnets therefore repel each other.
So that the neodymium magnets do not break or splinter, simply sink the magnets into the workpiece and protect the raw magnet from direct hits.
Note: If too much force is applied, neodymium magnets can break. We recommend a maximum tightening torque of 2 Nm when screwing on this magnet.

The product conforms to the European RoHS Community legislation (2002/95/EC - RoHS - Restriction of Hazardous Substances) relating to the use and the employment of certain hazardous substances in electrical and electronic devices.
Safety Notice
NdFeB magnets are hard and brittle. Especially with thinner dimensions / higher adhesive forces, these can easily break or splinter! An uncontrolled impact of two magnets as well as an external, mechanical shock or pressure load should therefore be avoided!
Determination of the magnetic force
The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N). A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded. Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.

Die Magnete halten bei mir Fliegenschutztüren (2 Stück/Tür). Sie sind kräftiger als es von der Beschreibung her zu erwarten war.
