These 1mm (0.04") thick diametrically magnetized neodymium ring magnets and 1.5mm (0.06") thick steel discs are the among the thinnest products in our range. Our thin diametrically magnetized neodymium ring magnets are not designed to provide the maximum pull strength but instead provide rotational movement for precision applications. The steel discs below are not produce any of their own magnetism but instead are used for installing a magnetic surface that magnets will stick to. For example, you could screw one of these discs into a wall and then, using magnets, hang artwork or noticeboards. Each disc can be fixed in place using an M6 countersunk screw.
