Countersunk magnets 12x4 mm. (N + S), 10-pack

Now you can buy these 12x4 mm. neodymium countersunk magnets as a set. Here you get 10 magnets: 5 pcs. with north pole and 5 pcs. with south pole, so they can attract each other from the countersunk side.

Diameter: 1.2 cm.
Height: 0.4 cm.
Screw hole: ø 4.5 mm. (M3)
Strength: approx. 1.6 kg.
Package: 10 pcs.

Be aware that the magnets are very strong and not protected by a steel pot. They must therefore be handled carefully in the process of screwing onto another surface so that they do not break, as the only protection is the nickel coating. You must never over-tighten the screw; but only screw it in until the flat screw head aligns with the surface of the magnet.

The strength is measured directly on a thick, magnetic steel plate. The strength weakens the further the pot magnet comes from the magnetic surface. Ususally, we produce our magnets with a density of N45 or higher, but because they become extra brittle in this small size with a screw hole in the center of 3 mm., we had to choose a smaller density of N35. However, you still get a very strong magnet.

Cannot be used on a magnetic glass boards.

We recommend this type of neodymium magnet for indoor use only. When subjected to wind and weather, power magnets rust over time, but it takes a long time before the strength weakens, as long as the magnet is not exposed to temperatures above 80 degrees.

SPECIFICATIONS
Strength: approx. 1,600 g.
Magnetism: N35
Surface: nickel-plated (Ni)

NOTE! Set of 10 magnets. You can use these magnets opposite each other as a set if you screw them onto two surfaces that are to meet magnetically, as the poles are facing opposite directions on the magnets. There are a total of 5 sets - so 5 of each type of pole reversal.
