Industrial Grade - This neodymium magnetic hook is made of neodymium magnets and steel, offering strong permanent magnetism and durability. Compact and lightweight with high magnetic strength, it firmly attaches to iron, steel, nickel, and other ferromagnetic materials. Bearing Capacity - Can support up to 25 lbs. Magnetic strength is reduced by approximately two-thirds when used horizontally. Note that magnetic performance may be affected by surface flatness, material type, and other environmental factors. For use on stainless steel refrigerators, it is recommended to place a protective layer such as tissue paper between the magnet and surface to prevent scratches. Versatile Use - These small and space-saving magnetic hooks are ideal for organizing keys, hats, towels, cups, aprons, purses, tools, kitchen utensils, workshop items, filing cabinets, wiring, and more. Suitable for use in bathrooms, kitchens, living rooms, garages, sheds, and workshops wherever metal surfaces are present. Perfect Hooks - A practical solution for hanging lightweight items indoors or outdoors on ferromagnetic surfaces.
