Undersænket pottemagnet, Ø16 mm. - Neodymium ludo mini Remember to measure the thicknessCountersunk magnets (shallow magnets) Diameter: 1. 6 cm. Height: 0. 52 cm. Screw hole: 3. 5 mm. Strength: approx. 6. 9 kg. These countersunk pot magnets can be fastened with a countersunk screw (3. 5 mm). They consist of a strong neodymium magnet encased in a steel cap (pot). The steel improves the adhesiveness of the magnet due to direct contact with a thick steel surface. The strength is always measured directly on a thick, magnetic steel plate. The
