Neodymium Iron Boron Magnet With Square Counterbore m4 Screw Holes and Black Epoxy Coating, 25x25x13mm
This is a black square magnet with a counterbore, made of rare earth neodymium. The specific dimensions are 25mm in length and width, and 13mm in thickness. The magnetization direction is along the thickness. This sample is coated with black epoxy resin, which can extend the service life of the magnet and prevent the magnet from corrosion and oxidation. This magnet has an M4 counterbore in the center, and this combination is very common when assembling some large objects. Selecting an epoxy resin coating for NdFeB magnets can provide good anti-corrosion protection. When NdFeB magnets come into contact with air, water, or other chemicals, it can prevent oxidation and corrosion, which is particularly important for magnets used in outdoor applications, humid environments, or in contact with chemicals. If you have any requirements for M4 hole magnets, please contact us, and we can customize the number and position of the holes for you.
