This round base rare-earth neodymium (NdFeB) cup magnet is made with A3 steel plate and coated with Nickel-Copper-Nickel to be the strongest type of permanent magnet available.
The magnet comes with a removable hook. Attach it to a wall to hold tools, or position and hold lights, signs, and more. This type of magnet is also perfect for magnet fishing and retrieving applications.
Please note that holding power of 80 lbs is tested on unpainted horizontal ½” steel plate. Mounting on a vertical or painted surface will reduce holding power by up to 70%.
