Product Details

Size: 40mm diameter x 10mm thick with 4.3mm countersunk hole for mounting

Quantity: 1

Grade: N45 Neodymium

Pole location:  Poles on flat faces

Pull/Push: About 30kg to a similar magnet or to 4.4mm sheet steel. 52kg for stacked pair. Between two plates, 63kg! The more pull, the more the danger! Resistance to sliding is about 1/3 of these figures. 

Notes:

  • If the magnet is too strong, glue 1 or 2 mm thickness of a non-magnetic material to the flat, pole surface
  • About 10 times more pull than the traditional, grey, ferrite type
  • This type of magnet never weakens with age
  • Triple plated for durability: Ni/Cu/Ni

Potential Uses:

  • Excellent for securely attaching all manner of fixtures to plate steel, or for a heavy gate. Consider "pot" type especially if the steel is thinner. They are cheaper.
  • Retrieving or "fishing" for lost steel items

Warnings:

  • Not for kids! Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • The material is brittle. It can chip or break during collisions. Eye protection advised.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
