8Pc Super Strong 24 lbs Neodymium Cup Magnet w/ Hook 5/8" Round Base Mounting Magnet Used as Tool Holder, Strongest & Most Powerful Rare Earth Magnets by Applied Magnets

Strong Cup magnets are made from neodymium magnets, the world's strongest magnets. Neodymium cup magnets provide much stronger holding power than ceramic cup magnets.
This handy and useful neodymium strong cup magnet has a strong magnet embedded inside a Nickel coated steel cup to offer the maximum gripping power. The steel cup offers protection for the magnet and concentrates the magnetic force on the magnet surface. A Nickel coated hook is attached to the magnetic cup through a threaded hole
Magnetic Cup Size: 16mm (5/8") Diameter x 37.5 mm (1.48") tall with M4 threaded hook attached.

Neodymium magnets are the world's strongest magnets. Applied Magnets offers the highest quality Neodymium cup magnet with consistent performance and lowest price. Our Neodymium cup magnets are designed and manufactured to meet stringent quality standards using the latest technology. Neodymium magnets (also known as Neo, NdFeB, NIB or Super Magnets), a type of rare earth magnets, are the permanent magnets made from Neodymium, Iron, Boron and other minor elements. Nickel-Copper-Nickel triple layer coated for maximum Neodymium magnets durability and protection against corrosion.

Warning:Neodymium magnets are very, very strong.
- Neodymium magnets are brittle; they can be broken or can splinter in a collision. One should wear gloves and protective glasses when handling these magnets, because splinters and/or spacers could disengage and fly from the magnets. (This is true with all Magnets)
- The strong magnetic fields of Neodymium magnets can damage pace-makers or other bodily implants, keep a minimum of 3 feet distance.
- Children should not be allowed to handle Neodymium magnets as they can be dangerous. Small magnets pose a choking hazard and should never be swallowed or inserted into any part of the body.
