Disc-shaped neodymium magnets with countersunk hole to use with countersunk head screws.
The magnet is made of neodymium, an iron/boron/rare earth alloy which is currently the most powerful magnetic alloy.
The magnet is coated with an anti-corrosion covering (chrome and nickel alloy) to protect it from chipping and cracking and to give an attractive finish.
The countersunk hole allows to fix the magnet with a countersunk head screw that won’t stick out from the magnet. This ensures that the screw-on magnet has a completely flat surface.
