Countersunk magnet 12x4 mm. (neodymium)

Round neodymium magnet with hole for countersunk screw - makes it easy for you to screw the magnet into anything you would like to make magnetic.

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

The round power magnet has a countersunk hole so that you can get a flat surface with a countersunk screw.

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! You cannot use 2 of these magnets opposite each other as the poles are facing the same way on all the magnets. Instead, choose a similarly sized magnet or piece of metal as a counterpart. Instead, choose a similar size magnet or metal counterpart with the same diameter of 12 mm. or bigger.
