CUPM Series (M Threaded Stud)
These Cup Magnets, also called Pot Magnets or Pot, have a male threaded stud and are designed to be mounted with a nut or screwed into a threaded hole. 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 CUPM Series (M Threaded Stud)
These magnet assemblies have a male threaded stud and are affixed inside a robust steel housing, and are designed to be mounted with a nut, or screwed into a threaded hole.
Often also referred to as POT magnets or CUP Magnets, due to the way they are assembled. 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.
The CUPM magnets have a male threaded stud.
Protective rubber boots are also available for further protection, and anti-slip properties.
