These pot magnets have a cylindrical borehole and can be fastened with a regular screw. We also carry a very similar pot magnet with countersunk borehole.Flachgreifer Zylinderbohrung – Neodymium pot magnets with step holes in the center are fixed by screws on the flat surface and the ferromagnetic metals can be attracted on the pot magnets by the neodymium magnets. Φ40mm Shallow NdFeB Pot Magnets with Cylindrical Hole

The magnetic base with hole and metric are magnets made of Neodymium, a material that is part of the rare earth, the latest generation of magnetic materials and is composed of an alloy of neodymium, iron and boron that provides great holding power for their applications. These magnetic bases can be used in temperatures up to 80ºC.
The magnetic base is a magnet in the form of a magnetic disk incorporating a through hole in its centre and a metric.
They are very similar to the countersunk magnets but the difference between the magnetic base with hole and metric and the countersunk magnets, is that the former has a metric to screw and fix the object in question better.
