  • These are ideal for a range of holding applications
  • Axially Magnetised through the thickness so that face with the countersink on is magnetised north, while the flat face is magnetised south
  • +/-0.1mm manufacturing tolerances on any dimension
  • Countersunk for an M6 screw

These Neodymium rings are countersunk to accept an M3 screw. They have many uses, including:

  • Fix them to walls and ceilings to suspend tools
  • Fix to doors to make magnetic catches (note, we do not supply steel plates).  If you require a two magnet hold, we stock the same size magnets with the countersink on the face magnetised north.


  • Neodymium magnets are unsuitable for children under 8.
  • All neodymium magnets are brittle. Do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter.
  • Overtightening a screw in these magnets will cause them to crack
  • Pull and Hold figures only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.

We aim to ship all items as soon as payment is cleared. This means that items ordered and paid for by 12 noon (UK time) Monday-Friday are usually dispatched on the same day. Items ordered and paid for after 12 noon or over the weekend are sent on the next working day. We never charge excessive amounts for postage and packaging. Our P&P charges are made up of the Royal Mail charge for the service plus a small contribution towards the packaging materials, plus VAT, which we are legally obliged to charge.

EU CUSTOMERS IMPORTANT: You are will be required to pay import VAT (tax) at your local rate to your postal delivery service before any goods are delivered. Since 2021 you have not been charged British VAT (at 20%) on any purchases, however, with effect from 1 January 2022, the rules regarding importing from outside the EU changed and import VAT is now payable on any value of goods imported into the EU. This is separate to any tariff which may or may not be chargeable on the goods due to their country of origin. Please also note that we are legally required to declare the correct value of your purchase which is used to calculate the tax and any tariff duty. Failure to pay the import charges will result in the goods being returned to the UK.
