Features: Size: 12 Pack Size: Diameter is 16mm, tiny but useful. Package including: The package contains 12 magnetic hooks, always have a spare. Each hook has 8 kg of direct pulling force. Magnetic hook hook high quality help; made of A3 steel and assembled nodymium-iron-boron, with these hooks to store keys, papers, kitchen utensils, tools, etc., you can easily find them. The finish Attractive polished nickel not only provides corrosion protection, but also makes your hooks look great; that you place them. They are usable for the arrangement of shops, lounges and the manufacture of furniture, for example for fixing heavy steel doors or gates, for hanging tools and displays, for attach advertising banners, protective signs and covers, etc. They are very useful in the kitchen, office, on bulletin boards, magnetic or interactive boards Caution: 1. Keep the magnetic hook away from children. 2. Do not place the magnetic hook near the electronic medical magnetism and the pacemaker. 3. Do not place the credit card, IC card, or any other card that could be decayed by a neodymium magnet. 4. Hook adsorbed on the metal surface of the required level in order to achieve the best results, the actual force of attraction is concerned. with the adhered material. In a vertical application (for example, the side of a refrigerator or toolbox), the force of the magnetic hook decreases by approximately 1/3 due to the forces of shear and friction of the surface. The thickness and content of the steel and the friction of the finish also have an effect.
