Mounting Magnets can double the strength of which you get with the magnet alone, as the steel cup attracting to it is magnetized by the magnet, giving much more pull force. The pull force numbers we list for each product is the force required to pull the mounting magnet straight away from a steel surface.

In fact, how much force a mounting magnet can hold depends on a few factors. When loading the magnet in a different orientation, for example, vertically stuck onto a wall, the weight it can hold up is usually lower than the listed pull force number. Moreover, the friction between the surfaces, the shape of what is being held up, and other factors also contribute to differences of the results.  

Powerful mounting magnets are often used as fishing magnets to retrieve objects that are lost underwater with magnetic parts or steel components. Mounting magnets with different features, such as hook, threaded and countersunk, can be widely used for holding, hanging, and attaching objects in different projects.
