Neodymium Countersunk Ring Magnet - OD25mm x 10mm C/Hole d12/6 | SOUTH
Powerful, versatile, and designed for secure screw fixing, this Neodymium Countersunk Ring Magnet features an outer diameter of 25mm, a 10mm thickness, and a countersunk centre hole with a 12mm outer countersink diameter and 6mm internal hole diameter. Manufactured from high-strength rare earth neodymium, this magnet is ideal for applications requiring a strong magnetic hold combined with a flush-mounted installation.
This version is supplied with the South pole on the countersunk face, making it ideal for specialised magnetic assemblies, paired magnet systems, and applications where a specific magnetic pole orientation is required. The countersunk design allows the magnet to be securely fastened using a suitable countersunk screw, creating a clean and professional installation while maintaining maximum magnetic contact across the face.
Finished with a durable NiCuNi nickel coating, this magnet offers excellent resistance to corrosion and wear while maintaining a polished metallic appearance. Its ring-shaped design and substantial thickness provide excellent magnetic performance for industrial, engineering, manufacturing, commercial, and DIY applications.

Please Note
Neodymium magnets are extremely powerful and should be handled carefully. Magnets may snap together unexpectedly and can chip or crack upon impact. When mounting with screws, avoid overtightening as excessive force may damage the magnet. Keep away from children, pacemakers, electronic devices, and magnetic storage media. Pole orientation is specified as South on the countersunk face.

Surface Treatment
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. We specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Magnetic Properties
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
