Female Thread Neodymium Pot Magnet | Stainless Steel Coating | 30mm x 16mm with ¼”-28 UNF Threaded Hole | N54
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This high-strength female thread neodymium pot magnet is engineered for heavy-duty holding and mounting applications where reliable performance and corrosion resistance are essential. Featuring a 30mm diameter stainless steel (SUS410) cup and a powerful N54 grade neodymium magnet, this compact assembly delivers an impressive 33kg pull force, making it ideal for industrial, workshop, commercial, and DIY uses.
The magnet is fitted with a 1/4" UNF half-internal female thread, allowing easy attachment of compatible bolts, eyebolts, hooks, or custom fixtures. Its notch-base design provides added stability and improved torque resistance, helping prevent rotation during installation or under load.
This magnet features a ¼”-28 UNF threaded hole with a depth of 10mm, designed for compatibility with imperial fasteners. Due to the fine imperial thread specification, standard M6 screws are not suitable for use. For proper fitment and optimal performance, a ¼-28 UNF bolt must be used instead of an M6 fastener.
The stainless steel pot protects the magnet from impact and wear while concentrating the magnetic field at the contact surface for maximum holding power. This design significantly increases performance compared to standard magnets of similar size.

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. We 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.
