Disc Shape Countersunk Neodymium Magnets
BEARHEART can provide Neodymium Countersunk Magnets, available in a wide range of sizes and grades, not all of which are shown on this website. Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family. Neo magnets have the highest magnetic properties and are the most powerful commercially available magnets today. Because of their magnetic strength, neodymium disc magnets are the preferred choice for many consumer, commercial and technical applications.

Features
Neodymium countersunk ring magnets are also called Neodymium countersunk magnets. All these Neodymium ring magnet variations are nearly always axially magnetized - the magnet is magnetized along its central axis. So one flat end face is a North pole and the other flat end face is a South pole. For pure rings, turning over the ring changes the polarity. But for the NdFeB countersunk rings and the NdFeB counterbore rings the countersunk or counterbore side will be a North or a South and the other end (which will visually look like a pure ring) will have the opposite polarity).

Applications
Flat countersunk neodymium disc and block magnets with one or two boreholes can be fastened with a countersunk head screw. They are only 4 mm thick and therefore very discreet for hanging up signs, tools, etc. Screw-on magnets are very popular in the areas of kitchen installations, booth and store construction, signage technology, furniture construction, etc.
