Neodymium Magnets
Made of neodymium, these rare earth magnets are the strongest for their size. The nickel-plated finish resists corrosion.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Multi-Pole Neodymium Magnets
Many small poles give these nickel-plated magnets shallower, more concentrated magnetic fields that hold especially well on thin material. To prevent accidental attachment, they won't attract until they're close to the material. Also known as Polymagnets®.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Neodymium Magnets with Unthreaded Hole
Made of neodymium, these rare earth magnets are the strongest for their size. Slide onto a rod or use a bolt or screw to install.
Choose a straight, countersunk, or counterbored hole. Magnets with a countersink on one side can be mounted with the North pole facing out.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Easy On/Off Magnets with Mounting Flange
Turn these magnets on and they won’t budge from metal surfaces; turn them off to reposition or move them out of the way. They have a flange with screw holes on either side, so you can mount them to fixtures, jigs, and other assemblies. When these magnets are on, they apply downward pressure to anything below the flange. They’re made of neodymium, a rare earth material, with a nickel plating or powder coating that protects them from corrosion. A steel case focuses the magnetic field and prevents damage to the magnet surface. Since the magnetic field is turned on or off mechanically, they don’t need a power source. Unlike threaded clamps, these magnets are easy to wipe down, so they won’t get clogged with welding spatter or sawdust.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
