Information
Retaining magnets GN 50.4 are a shielded magnetic system.
To ensure that the magnetic properties (magnetic forces) are not impaired,
the fixing screws of the types for countersunk screws and socket cap
• Materials of the magnet:
screws must be made of non-magnetic material (magnetic not conductive).
-- Hard ferrite HF
temperature resistant up to 200 °C
