This 4.72" diameter magnet is same size as our countersunk version but we have made significant improvements to the design to make it extremely strong. This magnet is made with A3 steel plate and coated with Nickel-Copper-Nickel to be the strongest type of permanent magnet available.
The threaded stud allows many types of mounting applications including hook, knob, or included stainless steel M12 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.
The forces have been determined at room temperature on a plate of polished steel (A36) with a thickness of 1/2 inch. The pull force is applied perpendicular to the face of the plate. A maximum deviation of -10% compared to the specified force is possible in exceptional cases, generally the value is exceeded. Depending on the type of application (thickness/condition of base metal, temperatures, and direction of pull), the forces can be influenced enormously. Mounting on vertical surfaces can reduce the pulling force by up to 70%.The indicated values solely serve a basis for comparison under above stated conditions.
