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 available with either pole on the magnetic face so that they can be used as a pair to attract or repel. If you are using two magnets to attract you need to make sure the opposite
poles are facing each other as identical poles will repel! Some of their uses include:
Cabinet making – Typically you’ll find countersunk magnets used as invisible closing mechanisms and soft drawer closures.
DIY – Neodymium magnets can be used to create gate latches, holding doors open and closed, fixing bath panels and creating removable access panels.
Shop fitting – Magnets are often used in shelving and lighting systems, screens, window displays and signage.
Regular countersunk magnets are the only suitable choice if you need magnets to work through a gap, while countersunk pot magnets work best when clamped directly against a steel surface.
Make mounting Magnet Easier Using Neodymium Magnets With Countersunk Holes
Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw.
If your project requires magnet-to-magnet application, use North pole with South pole magnet to avoid the magnets repelling.
