Ferrite pot magnet

with counterbore, Ø 40 mm
currently not deliverable


These ferrite magnets can be mounted with a countersunk head screw. They feature a lower adhesive force than similarly built CSN, but they have the following advantages:
  • Lower-priced than neodymium pot magnets
  • Can be used outdoors (pots may develop a rust film, which does not impair their function)
