This is a rubber coating coutersunk hole ring magnet, which is made of rare earth neodymium element, the countersunk hole is a threaded hole, this magnet can use with M4 screw. The specific size is 40mm in outer diameter, 5mm in inner diameter, 6mm in thickness.
Rubber coated magnet, also referenced as rubber covered magnet or weatherproof magnet, is mainly made by sintered Neodymium magnet, stainless steel plate, and durable rubber coating.But remember to distinguish between coated magnets and rubber magnets.
Size diagram of strong magnet with threaded hole(M3-M6 Optional);
Rubber magnets are manufactured by extrusion or calendering and can be widely used anywhere from offices, warehouses, garages, dining rooms, classrooms. Compared to other kinds of magnets, rubber magnets exhibit great flexibility, and they can be bent, twisted, coiled, slotted, punched, or otherwise machined into almost any shape without loss of magnetic energy. We can manufacture flexible magnets to your final desired size and color.
Rubber coating magnet has high durability and high friction, preventing the magnet from sliding on the surface, and the rubber coating also protects against liquid, moisture, corrosion and fragmentation. Prevents scratching cars, trucks, delicate surfaces, etc.,
