Description Features: Magnetic hook using high quality neodymium-iron-boron assembled, with these hooks store keys, papers, kitchen utensils, tools, etc., you can easily find them. The attractive polished nickel finish not only provides corrosion protection, but also makes your hooks look great wherever you place them. They can be used for fitting out shops, trade fairs and manufacturing furniture, such as for fixing heavy steel doors or gates, for hanging tools and displays, for attaching advertising banners, tarpaulins and covers, etc They are very useful in the kitchen, office, on bulletin boards, magnetic or interactive boards Size: Diameter is 16mm, tiny but useful. The package contains 12 magnetic hooks, always have a spare. Each hook has 0-8kg of pulling force. Caution: 1. Keep the magnetic hook away from children. 2. Do not place the magnetic hook near the electronic medical magnetism and pacemaker. 3. Do not place the credit card, IC card or any other card could be demagnetized by neodymium magnet. 4. Hook adsorbed on the metal surface of the required level In order to achieve the best results, the actual attraction force is concerned with the adhered material. In a vertical application (for example, the side of a refrigerator or a tool box), the strength of the magnetic hook decreases approximately 1/3 due to shear forces and surface friction. The thickness and content of the steel and the friction of the finish also have an effect.
