Countersunk magnets screw-on
Countersunk pot magnets screw-on In these products, our neodymium magnets are sunk in a steel pot and have a centered borehole and countersink. Hence, they can be screwed into the wall or ceiling with an appropriate countersunk screw and you can attach various objects. Besides countersunk pot magnets made of ferrite, you can also find pot magnets with cylindrical borehole as well as screw-on magnets without pot in our assortment.

Use as holding, mounting or cup magnet
Especially suitable for structural solutions in metal, plant or booth construction as well as in the lighting industry

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.
