  • A neodymium magnet housed in a steel “pot”.
  • Extra durable.
  • The highly-localised field is across a narrow ring on only the countersunk side.
  • They pull best to flat steel, eg thick washer.
  • Not for pulling from a distance, or to another magnet, or motors. Use a STANDARD magnet for that.
  • Still pulls strongly when set into steel.


  • 16mm diameter x 5.1mm thick.
  • Mounting hole.
  • Quantity: 12
  • Pull: About 5kg to 1.7mm sheet steel. Resistance to sliding, about 1/3 of that.
  • Neodymium magnets never weaken with age.
  • About 10 times the pull of traditional ferrite types.
  • Triple plated for durability: Ni/Cu/Ni.


  • Holding tools, knives etc.
  • Closures for doors etc. Sorry I don't have washers.
  • Holding panels & fittings to steel walls.
  • When magnetic fields must be kept to a minimum.


  • Not for kids. Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
