This guide is for DIY enthusiasts, crafters, and workshop users who need reliable magnetic holding solutions. The B&Q Ferrite Pot Magnet offers outstanding value and a strong, convenient mounting option. While cost-effective, it's important to note its lifting capacity is dependent on surface conditions.

The magnet can support up to 11.4kg vertically when in flush contact with a mild steel surface of equal thickness. This is a theoretical maximum and actual holding force may vary based on surface conditions.
The magnet itself is made of ferrite, and it is housed within a chrome-plated steel shell.
The magnet features an M5 external thread, which allows it to be screwed into a tapped hole, a countersunk hole (with a suitable fastener), or onto a threaded stud.
The chrome-plated steel shell offers some protection against corrosion, but prolonged exposure to harsh outdoor elements is not recommended. Keep them clean and dry for best performance.
Ferrite magnets are generally less powerful than neodymium magnets of the same size, but they offer a more cost-effective solution and are still very strong for many applications.
The magnet has a diameter of 40mm and a thickness of 8mm, with an M5 external thread.
Each pack contains four ferrite pot magnets.
Ensure the mating surface is clean, flat, and made of mild steel. Check that the steel surface is thick enough to support the magnetic field. Try to maximize the contact area between the magnet and the steel surface.
Inspect the thread for debris or damage. If damaged, the magnet may need replacement. Ensure you are using the correct size tapped hole (M5).
Avoid exposing the magnet to high temperatures or strong opposing magnetic fields. Store magnets separately if not in use to prevent them from attracting each other excessively, which can slightly reduce their individual strength over long periods.
Setup: To mount, simply screw the M5 external thread into a compatible tapped hole, a countersunk hole with an appropriate fastener, or directly onto a threaded stud. Ensure the threaded connection is secure.
Compatibility: These magnets require a clean, flat, mild steel surface for optimal performance. They are most effective when the steel surface is at least as thick as the magnet's diameter. They are not suitable for use on non-ferrous materials like aluminum or plastic.
Care: To maintain magnetic strength and the integrity of the steel shell, clean the magnets with a dry or slightly damp cloth. Avoid exposing them to extreme temperatures (above 80°C) or strong opposing magnetic fields, which can cause demagnetization. The chrome-plated steel shell offers good protection against corrosion and minor impacts.
