Pot Magnet with Through Hole Mounting is available in sizes from 8mm to 150mm diameter with pull forces ranging from 0.5kg up to 500kg. The holes could take M3,M4 M5, M6, M8 and M10 threads. The inner diameter of the ring magnet is much larger than the hole in the steel casing allowing the head of the bolt or screw to easily fit in place.The Mounting Magnet with Through Hole Mount contains a ferrite or NdFeB ring magnet within a steel casing. The steel casing is plated to give high corrosion resistance. The steel casing has a hole in it to allow the Pot Magnet with Through Hole Mounting to be easily fixed into position with a cap screw or a bolt into the boss. The design is extremely robust.

An advantage of this design is that the fixing is done by clamping onto the steelwork rather than the magnet, allowing higher then normal tightening to be possible to ensure maximum secureness of fitting (such high clamping forces directly on magnets could break the magnets).
The Pot Magnet with Through Hole Mounting has a good depth of field which enables the larger magnets to be used as a retrieval magnet. The Pot Magnet with Through Hole Mounting is ideal for use in heavy duty or industrial fixing applications.
The Pot Magnet with Through Hole Mounting also exists in a rubber coating version to provide additional friction to minimise sliding along a surface.
