What do you use this magnet for?

Suitable for light closures, displays, interior construction and model building. With the countersunk hole you can screw the magnet flush onto wood, plastic or metal, for example for cabinet doors, displays, signs and closures. Do not overtighten the screw: neodymium is brittle and can crack. This is the North pole version; there is also a version with the opposite pole, so you can make magnets attract or repel each other. Which ring magnet should you choose?

The holding power is measured under ideal conditions on a flat steel plate; in practice, the actual holding power is lower. Read how holding power is determined.
