Extremely strong, high-performance Neodymium (N42) magnet encased in and sealed in welded stainless steel complete with counter-bored hole on the front and M10 thread in the back.
These incredibly powerful magnets combine the strength of Neodymium with the corrosion resistance of stainless steel making them ideal for outdoor applications or in environments where they will come into direct contact with water. They also produce a large depth of magnetic field, maintaining a strong magnetic pull even when there is up to a 30mm air gap between the magnet and the material it is attracting. Each magnet is counter-bored on the north face and can be fixed in place using an M10 bolt. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.
