CUPI Series (Internal Thread)

CUPI Series (Internal Thread)

These Cup Magnets, also called Pot Magnets or Pots, have an internal thread all the way through the part. They can accept screws, eye hooks, or other threaded hardware and have a lower profile than the CUPF series. The steel housing protects the magnet and focuses its magnetism on one side, increasing its strength when attaching directly to flat magnetic surfaces. They are compatible with rubber boots for further protection and anti-slip properties.

Additional Product Information for CUPI Series (Internal Thread)

These magnet assemblies have an internally threaded insert, and have Neodymium Magnets which are affixed inside a robust steel housing, and are designed to be attached with screws.

The outward facing side of the Neodymium Magnet has a polarity that faces North, and due to the magnetically conductive nature of the steel cup, it causes the outer portion of the steel cup to have a South facing pole.

Protective rubber boots are also available for further protection, and anti-slip properties.

Neodymium Magnets (NdFeB)

Neodymium magnets (NdFeB) are the strongest permanent magnet material commercially available.
