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