	What internal threaded pot magnet sizes are available?

			Internal threaded pot magnets are always measured diameter x depth. The size of the shell is usually included within the measurements.

			Shallow internal threaded pot magnets
			Diameter The diameter refers to the distance between the two widest points of the magnet and ranges from 19mm (0.75″) to 100mm (3.9″).

			The diameter you choose will depend on the size of the object the pot magnet is needed to hold, (e.g. a set of keys). An internal threaded pot magnet with a smaller diameter may provide a more aesthetically appealing end result, compared with an internal threaded pot magnet with a large diameter.

			Depth The depth of a shallow internal threaded pot magnet is the distance between the top of the shell and the magnetic face. This usually increases as the diameter does, and can range from 7mm (0.28″) to 20mm (0.79″).

			Magnetic pull The magnetic pull ranges from 3.6kg (7.9lbs) to 55kg (121.25lbs).

			The magnetic pull is the maximum weight of ferromagnetic material the internal threaded pot magnet can hold. This is not determined by its overall size, but by the material the magnet is made from. This means that a large magnet does not necessarily have a larger magnetic pull than a small magnet.

			Summary
			To summarise, when purchasing an internal threaded pot magnet, the key thing to look out for is the diameter, as this has the greatest effect visually on the end product.

			Deep internal threaded pot magnets
			Diameter The diameter refers to the distance between the two widest points of the magnet and ranges from 6mm (0.24″) to 80mm (3.15″).

			Depth The depth of a deep internal threaded pot magnet is the distance between the top of the shell and the magnetic face. It can range from 20mm (0.79″) to 65mm (2.56″).

			Magnetic pull The magnetic pull ranges from 0.2kg (0.44lbs) to 155kg (341.72lbs).

			Summary
			The size of deep internal threaded pot magnet you choose depends upon the size of the non-ferromagnetic material you are attaching it to. The size of the pot magnet needs to be sufficient enough to hold onto the object without becoming unstable. For example, for a large and heavy gauge, you will need a large depth and diameter pot magnet in order to stop the object from falling over.
