About Magnets

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. Magnets with a countersink or counterbore on both sides can be mounted with either the North or South 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.

Multi-Pole Neodymium Magnets with Unthreaded Hole
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. Slide onto a rod or use a bolt or screw to install. 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.

Encased Ceramic Magnets with Unthreaded Hole
A case protects the magnetic material. Steel cases also concentrate and focus the magnetic field. Ceramic magnets resist demagnetization better than other magnets and are an economical choice.
A keeper covers the poles to preserve the strength of the magnet and protect it from attracting metal during storage.
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.

Push-to-Open Magnetic Latches
Close and open these magnetic latches with a push—there's no need for a handle. Magnetic force holds doors closed. Note: Maximum pull-strength rating given is based on installation with the furnished strike plate; pull strength may be different based on the application.
Each latch has a wraparound and flat strike plate. Styles 5 and 6 have two-piece strike plates for double doors that meet in the center.
