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.
Magnets with poles magnetized through the diameter are often used in rotation sensors.
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.

Machinable Magnets with Unthreaded Hole
These magnets are bonded with epoxy resin, so they can be machined with carbide tooling. Slide onto a rod or use a bolt or screw to install.
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.

Routing Rings
Also known as bridle rings, routing rings have an open-eye design that allows you to quickly install wire and cable. Press-fit routing rings mount onto beams and other flat surfaces. A hole on the back of the jaw allows you to orient the ring horizontally. Lightly hammer to install. Magnetic routing rings provide a temporary hold on steel and iron surfaces.
