Product code: AMFYPA20N/S
This north and south pair of rare earth countersunk pot magnet have a diameter of 20mm, a countersunk hole diameter of 4.5mm and a thickness of 7mm. It has a pull force of 6kg and a weight of 13 grams. It is identified by the AMF magnet part number AMFYPA20NS.
Capped countersunk Holding magnets have a greater holding capacity than standard uncapped disc magnets and are extremely useful tools for attaching various items to steel surfaces. These countersunk Holding magnets have an additional feature of countersunk North and South matched poles that attract to each other instead of repelling. When screwed onto opposing surfaces, a magnetic bond is created which is reciprocal and does not require the presence of ferrous material to operate. Unlike traditional, less practical fasteners, a magnetic bond can be broken and then reinstated as often as required, in a time-saving and efficient manner that is instantaneous and does not require tools or DIY skills. Paired magnets, with complementary poles that attract to each other, allow any two types of surfaces to attach magnetically. Unmatched Holding-type magnets will attach to each other to some extent, but not with the precision and accuracy exhibited by these paired magnets with matching North to South poles.

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.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics 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.
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.
