Neodymium Magnets with Countersunk Holes N35,N36,N42,N45, 50 & N52 A Countersunk hole in a magnet provides a convenient way to fix the magnet onto a surface securely using a matching screw. Most of often there is a question about which polarity do I need for my application. The rule is if you use this magnet to attract to a steel surface, you can simply choose no preference; But if you are planning to use these magnets to attract to each other, you need choose half of your order to be north and the rest half of your order to be south; If you plan to use this magnet to attract to your own magnet, you need choose the opposite pole to match them up.
Countersunk magnets, are composed of neodymium magnets with a counterbore hole,Countersunk hole neodymium magnets are with various sizes of discs or rectangles shapes.Neodymium Countersunk Magnet, are perfect for use as magnetic fasteners around the home or for use in commercial applications.Use the countersunk magnet with wood frames is a good DIY activity for holding tools and objects,furnitures and more…
The neodymium Countersunk Magnet is a neodymium, iron, and boron magnetic alloy blend.The magnets are with anti corrosion plating. The North and South poles are on the largest flat directions.Please note that countersink block magnets are materials with strong magnetism and fragile features which require cautions when operating them.
