Neodymium countersunk magnets are a functional type of permanent magnets. These magnets have a countersunk hole, so they are easy to fix onto surfaces by using a matching screw. Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family. Countersunk neodymium magnets have the highest magnetic properties and are the most powerful commercially available magnets today. Because of their magnetic strength, neodymium countersunk magnets are the preferred choice for many consumer, commercial and technical applications.
Stanford Magnets is specialized in manufacturing and supplying neodymium countersunk magnets applied in various industrial applications. We have advanced technology, rich experience, and professional engineering technicians in this field.
