Product information "Ringmagnet countersink Ø 25.0 x 4.5 x 4.4 mm plastic coating - black"
The magnets with hole and countersink are also ideally suited to screwing them in the desired positions.
The north pole of this magnet is on the depression side.
Note: You cannot use two of these magnets in pairs, i.e. the magnets do not stick to one another with the countersunk side, but repel each other.

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.
