They work well
The size & thickness is as stated. The magnet has been used in a hole in steel. With the threaded part cut off it fills the gap with increased grip than a straight magnet of the same size. :)

This rare earth female threaded pot magnet has a diameter of 25mm, a total height of 17mm and a magnet housing thickness of 10mm. It has a 5mm female thread. This female threaded magnet has a pull force of 22kg and a weight of 32 grams. It is identified by the AMF magnet part number AMFYPD25.
These Neodymium Pot magnets have a Female Thread that allows them to be attached to any surface with a bolt. The steel capping protects the magnet from damage and redirects the magnetic flow towards the base for increased holding ability. Alternatively, a threaded rod or bar can be inserted to attach or display advertising and then attached to metallic surfaces. This enables them to be easily removed and replaced as required.

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
