The magnets in this listing are grade N52. The magnets are triple coated nickel-copper-nickel for good corrosion resistance and these magnets are magnetized axially giving a north pole on one flat face and a south pole on the opposite face. These high-powered 10mm x 3mm x (3mm hole) Neodymium Countersunk Magnets are very powerful and versatile. Perfect for drilling or fixing into place due to their countersunk hole, they are commonly used for DIY, crafts, woodworking, furniture making, and science experiments. They also have many uses in engineering and manufacturing where small size and maximum strength are required.
