Our range of 40mm countersunk magnets offer pulling forces of up to 33lbs and are now available in neodymium and ceramic magnetic materials.
These countersunk magnets are the largest in our range and manufactured for specialist applications. Our 40mm (1.57") diameter rubber-coated countersunk magnet is made from neodymium, the strongest magnetic material in the world. Their rubber coating makes them ideal for using to attract fragile or easily marked surfaces as it increases friction, softens impacts and prevents marking. Our 40mm (1.57") ceramic countersunk pot magnets are great value and impressively strong as their steel casing increases their adhesive force.
