How to use a countersunk pot magnet

Industrial sized fridge freezer

Countersunk pot magnets can be attached to non-ferromagnetic materials with the help of a countersunk screw; for example, to hold heavy fridge doors open and closed.


To attach the countersunk pot magnet to a non-ferromagnetic material, you will need to do the following:

Countersunk pot magnet, countersunk screw, cordless drill driver, forstner drill bit

Equipment required:

  • 22.23mm (0.88") forstner drill bit

  • Cordless drill driver

  • 12.7mm (0.5") countersunk screw, such as a wood screw

  • 19.05mm (0.75") countersunk pot magnet

  • Slotted screwdriver

Forstner drill bit drilling a hole into a piece of wood for the magnet

Step 1 - Drill hole

Use the cordless drill driver with the forstner drill bit attached to drill a flat-bottomed hole into a piece of non-ferromagnetic material, e.g. a piece of wood.


The forstner drill bit will produce a hole of a consistent depth with smooth sides, which is ideal to insert the countersunk pot magnet into.

Flat drill bit

A flat drill bit may also be used for this task, however it will not leave as neat a hole as the forstner drill bit due to its sharp pointed end

Step 2 - Insert countersunk magnet

Clear the hole of any wood chippings and insert the countersunk pot magnet with the countersunk hole facing upwards.


Step 3 - Fasten with screw

Fasten the countersunk magnet with the flat headed screws using a screwdriver. Continue doing this until the screw is flush (level) with the top of the countersunk pot magnet.
