Neodymium Pot Magnet with Round Hole - 16mm x 5mm
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This strong Neodymium Pot Magnet has the surprising pull force of 4kg while only being 16mm in diameter and 5mm in height. The high strength magnet is encased in a mild steel cap for extra protection against chipping and corrosion. The magnet is single-sided due to this protective mild steel casing on one side. It has an inside diameter of 3.5mm and an internal flange hole of 6.5mm.
The straight sided hole allows simple fastening to almost any surface material such as timber, plastic or masonry to name just a few. Easily attach with a screw or bolt inside the hole at the centre of this magnet for a professional finish. There is no need mess around with glue that may damage your surface or perish and discolour over time. Screws stay true, making them the unsurpassed fixing solution.
These Magnets are very popular with Tradespeople and Fabricators because of their range and adaptability. The ease in which these can be adhered also makes them ideal for the home DIY uses. Fantastic for door latches, or closing mechanisms, simply recess the countersunk magnet into your door frame and attach a metal strip or strike plate to the door. Magnets are useful for a whole range of applications in remediating an assortment of issues around the workshop, warehouse or garage.
Rare Earth Neodymium magnets are the strongest permanent magnets commercially available and are the ideal magnet if you require maximum magnetic strength. They are up to seven times stronger than traditional magnets and come in a huge range of sizes, shapes and grades. Rare Earth magnets are magnetically stable and have a strong resistance to demagnetisation however they are not suitable for use in high temperature applications.

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. 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.
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.
