Neodymium Magnets with Countersunk Holes N35,N36,N42,N45, N50 & 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 neodymium magnet, flat countersunk magnet, countersunk rare earth magnet, ndfeb countersunk magnet, super strong holding countersunk magnet
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
Rare Earth holding magnets with countersunk holes are designed for screws to be used for permanent positioning, leaving the screw head flush with the magnet.
Rare Earth pot magnets are high strength rare earth magnets in a mild steel cap for extra protection against chipping or cracking. Due to the protective cover on these pot magnets, they are single sided magnets which provide an easy, non-destructive solution for attaching and suspending objects.
These neodymium rare earth pot magnets have a central countersunk hole and can be used for many commercial or residential purposes. These high strength rare earth magnets are designed to allow the magnet to be easily fastened into place with a screw, leaving the screw head flush with the magnet. They can be easily screwed onto shelves, boards, walls or floors.
