Pot Magnets

Neodymium cup magnets with countersunk holes for fast mounting and extra strong holding.

Great for supporting signs or other objects in a vertical configuration.

Magnet holding strength radiates in all directions but a steel cup concentrates it to effectively increase pull strength by more than double.

These are ideal for magnet mounted antennas or for hanging various types of metal hardware.

This may be more cost effective than using N52 grade which only increases holding by ~20% over N42.

More Information

Note that the size of screw indicated for these magnets are standard metric sizes such as M3, M4, M5, etc. However, you can mount them with standard screws as long as they have a tapered head. Be careful not to overtighten since the neodymium magnet is brittle and can crack if stressed.
