These neodymium cup magnets are glued into indentations when it is impossible to screw them on. They have a higher adhesive force than same-size countersunk pot magnets because the contact surface is larger.
Please note: The magnets are not self-adhesive; a suitable adhesive is linked under accessories.
Please note: The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the pot magnet makes direct and full flush contact. Pot magnets already lose much of their adhesive force at a distance of only half a millimetre to the ferromagnetic surface. This characteristic is more pronounced in pot magnets than in other ferrite and neodymium magnets. You can find additional fascinating information on our FAQ page about pot magnet features.
