POT MAGNET

Product Code: PM90

1/4″-20 female thread1.42″ base diameter

The PM90 pot magnet offers an easy-to-use method of securing various hangers to metal surfaces. It can be used in a multitude of applications.

The PM90 features 1/4″-20 female threads that are 1/2″ deep.

Doc’s Pot Magnets (PM90) have a magnetic core made of neodymium, which is sunk in a steel pot in order to intensify the adhesive force of the magnet. This is why they are called “pot” magnets. They have a nominal breakaway strength of 90 pounds set by the factory. However, there are many factors that can influence the breakaway load, such as the composition and thickness of the base metal, the direction of the load whether mostly tension or shear, any coating on the base metal, the finish of the base metal and anything that effects the coefficient of friction between the magnet and the base metal. Therefore, it is a good idea to test each new application by setting the magnet and then giving it a tug to ensure that the breakaway strength is sufficient for your application.

Questions

Frequently Asked Questions

What is the purpose of a pot magnet?

The PM90 pot magnet secures hangers, brackets, or accessories to steel or ferrous metal surfaces without drilling or fasteners.

How strong is the PM90 pot magnet?

It has a nominal breakaway strength of 90 lbs under ideal conditions. Actual holding strength depends on the surface and how the load is applied.

What affects the holding strength of the magnet?

Holding strength varies based on surface thickness, surface finish, coatings or paint, load direction, and whether the load is in tension or shear.

Does the surface type matter?

Yes. Clean, flat, uncoated steel surfaces provide the strongest hold. Painted, thin, or uneven surfaces reduce holding power.

Does the pot magnet have threads?

Yes. The PM90 features 1/4"-20 female threads with a depth of 1/2", allowing compatible hangers or hardware to be attached.

Should the magnet be tested after installation?

Yes. Always set the magnet in place and apply a light pull test to confirm the holding strength is sufficient for the application.
