Epoxy Coated Neodymium Magnet Block With Countersunk Hole
Products description
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 ring magnets are the preferred choice for many consumer, commercial and technical applications. neodymium ring magnets supplier.
Neodymium countersunk magnet is a Neodymium ring magnet with one side appearing as a standard ring but the other side has an angled countersink to take a screw head, the angle usually being (but not always) 90 degrees. A Neodymium counterbore ring magnet is a ring magnet with a cylindrical flat-bottomed hole on one side that enlarges the main central hole to take a cap head screw.
How to safely separate the ring neodymium magnets?
Applications:
Neodymium magnets with countersunk are ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, NdFeB countersunk magnets have a central hole that allows them to be fixed to non-magnetic surfaces with a screw.
