This Rare Earth male threaded pot magnet has a diameter of 42mm, a total height of 20mm and a magnet housing thickness of 9mm. It has a M6 thread with an external boss of 11mm, the M6 thread's pitch is 1mm. This male threaded magnet has a pull force of 68kg and a weight of 84 grams. It is identified by the AMF Magnetics part number AMFYPC42.
This Male Thread Holding Pot magnet has a strong 68 kg holding capacity and is suitable for industrial applications. The projecting male threaded boss allows for simple attachment to non-ferrous materials using a washer and nut. Likewise, it can be incorporated as a component part into bespoke designs that are created for the customer’s particular application. The Neodymium magnet is protected by a mild steel cup which enhances the magnetic field at the working face of the magnet by projecting both poles through the operational side of the magnet. This increases the pull-force beyond the strength that a stand alone disc magnet would be capable of.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
