Neodymium Countersunk Ring Magnet - OD12.5mm x 6mm C/Hole d3/d9 | SOUTH
Compact, powerful, and designed for secure screw mounting, this Neodymium Countersunk Ring Magnet features an outer diameter of 12.5mm, a 6mm thickness, and a countersunk centre hole with a 3mm internal hole diameter and 9mm countersunk diameter. Manufactured from high-strength rare earth neodymium, this magnet is ideal for applications requiring a strong magnetic hold in a compact, screw-fixable design.
This version is supplied with the South pole on the countersunk face, making it suitable for specialised magnetic assemblies, paired magnet systems, and applications where pole orientation is important. The countersunk hole allows the magnet to be mounted flush using a suitable countersunk screw, providing a neat, 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 compact size makes it ideal for cabinetry, display systems, product design, workshop fixtures, engineering projects, electronics, and custom fabrication applications where space is limited but strong magnetic performance is required.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Small magnets can present a swallowing hazard and must be kept away from children. When mounting with screws, avoid overtightening as excessive force may damage the magnet. Keep away from 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.
