Technical Specifications

  • These are from our BUDGET RANGE of magnets, ideal for the budget conscious when the tolerances are less important than normal.  Instead of our usual +/-0.1mm tolerances, they have +/-5% tolerances on any dimension.
  • Outer Diameter: 15 mm (0.59")
  • Inner Diameter: 5.15 mm (0.20") - will take and M3 screw.
  • Diameter of Countersink: 6.75 mm (0.27")
  • Thickness: 10 mm (0.39"")
  • Axially Magnetised through the thickness.
  • Weight: 10.72g
  • Grade: N38
  • Coating: Ni-Cu-Ni (Nickel-Copper-Nickel)
  • Maximum Temp: 80°C / 176°F
  • Approximate Maximum Pull: 12.46lb / 199.3oz / 5650g (does not take account of Countersunk)
  • Calculated Max Vertical Hold-guidance only: 2.49lb / 39.9oz / 1130g (does not take account of Countersunk)
  • WARNINGS:
    • All neodymium magnets are unsuitable for children; do not ingest.
    • 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.
    • Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half.

These Neodymium rings are countersunk to accept an M5 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).

The pull is calculated using a mathematical formula and is, therefore, the theoretical maximum hold between one magnet and a mild steel plate. It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.

WARNING: 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. THIS IS NOT A TOY. DO NOT INGEST
