CUPF Series (F Threaded Post)
These Cup Magnets, also called Pot Magnets or Pots, have a female threaded post that can accept screws, eye hooks, or other threaded hardware. 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 CUPF Series (F Threaded Post)
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 CUPF magnets have a female threaded post.
Protective rubber boots are also available for further protection, and anti-slip properties.
