PRODUCT DETAILS
• 40mm diameter x 10mm thick.
• 4.3mm countersunk hole for mounting. (#8 self-tap screw)
• Quantity: 1
• Grade: N45
• Poles: Same polarity on each countersunk side.
• 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. 
• About 10 times more pull than a traditional ferrite-type magnet.
• Neodymium magnets never weaken with age.
• Triple plated for durability: Ni/Cu/Ni.

POTENTIAL USES
• Excellent for securely attaching all manner of fixtures to plate steel, or holding a heavy door or gate open or closed. For outdoor use, seal against weather. Consider "pot" type in various sizes, especially if the steel is thinner. They are cheaper.
• Retrieving lost steel items. 
• "Fishing" for steel items.
• Too strong? Glue 1 or 2 mm thickness of a non-magnetic material to the flat, pole surface.

WARNINGS
• Not a toy! They can easily pinch flesh 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.
