Pot magnets with countersunk hole (10)
A pot magnet with a countersunk hole is screwed in place with a countersunk screw. The screw head falls into the recess and sits flush with the contact surface. This keeps the magnet firmly and tightly in place, and it holds onto steel without glue. We supply them from Ø13 to Ø75 mm. The steel pot concentrates the force at the front, making them much stronger than a loose magnet of the same size.
