This product features a neodymium rare earth magnet encased in a compact metal cup, designed to securely attach to surfaces with a centre hole. Perfect for organizing kitchen utensils, gardening tools, and mechanical or handyperson equipment, it offers easy installation and removal for convenient use. Simply screw it into any non-metal surface and attach metal items for reliable holding. It is also suitable for securing metal objects on wooden surfaces using appropriate screws.
IMPORTANT NOTES:
The holding force of these magnets is rated when in direct contact with mild steel 10mm or thicker. The theoretical force stated applies to horizontal holding on a minimum 10mm steel surface. If the magnet is positioned vertically, the force should be divided by 3 due to the effects of gravity and reduced friction. It is important to avoid attaching these magnets to items made of alloy, stainless steel, Colourbond steel, or surfaces that are painted, oily, rusty, or bumpy as it can weaken their magnetic strength. Additionally, the magnet may be weaker if the item it is attaching to is thin, such as foil or sheet metal. If there is something in between the magnet and the surface it is attaching to, such as fabric, the pull strength will also be reduced.

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.
