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 countersunk hole allows many types of mounting applications including hook, knob, or included eyebolt. Screw it into 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 500 lbs (226.8kg) is tested on unpainted horizontal 1.27cm steel plate. Mounting on a vertical or painted surface will reduce holding power by up to 70%.
