Measurements:

Undersænket pottemagnet, Ø12 mm. - Neodymium Auto-translated (EN) We have it in manyCountersunk magnets Diameter: 1. 2 cm. Height: 0. 5 cm. Screw hole: 3. 5 mm. Strength: approx. 3 kg. The clever thing about a countersunk pot magnet is that you can screw it in with a countersunk screw. The thick steel pot increases the adhesiveness of the magnet in direct contact with a thick steel surface. All dimensions are stated incl. the steel pot, so that is the total measure. The strength is measured directly on a thick, magnetic steel plate.
