Dimensions and specifications: Diameter of the steel plate 16 mm. Adhesion / retention 8 kg. Versatility: You can use these eyebolts in the kitchen, bathroom, model making, workshops, assembly, inserts and many other places around the home and office. Blink hole magnets can be used to hold various objects.and many other places in the home and office. Blink hole magnets can be used to hold various objects. High quality materials: eye bolts (rings, eyelets, eyes) and pots made of galvanized steel, embedded Wukong NdFeB neodymium magnets; The same applies to galvanized surfaces, threaded eyelets and eyebolts. Durable: Ni+Cu+Ni triple layer coating provides shiny and rust-resistant performance. The steel cup will protect the magnet from chipping or cracking. Neodymium is a kind of rare earth metal, it is suitable in the manufacture of permanent and powerful magnets. This magnet has a permanent magnetism, it will be the same powerful, even decades later. Magnetic surface On a magnetic vertical surface, the pulling force of the hooks is 80 lbs! On a magnetic horizontal surface, the force of the hooks is about 15 pounds! The smoothness of the surface and the thickness of the steel also have an impact on the tensile strength of the hooks Small size with strong magnetic Easy to install: no need to drill, no hole leaves! You can hang towels, hammers, paint brushes, power cords, brooms, racks, hats, coats, aprons, bags, and pretty much anything you can think of on it. Note Do not let children play with them unsupervised as they could be injured. Keep magnets away from pacemakers and magnetic storage devices such as cell phones, bank cards and computers.
