Neodymium Ring Magnet - 12.5mm x 3mm x 6mm | North Countersunk Face

Neodymium Ring Magnet Product Description:

Similar to Disc Magnets in shape, this strong magnetic ring is distinguished by its countersunk hole. This product has an outside diameter of 12.5mm, an inside diameter of 3mm and a countersunk hole through the north face. It is 6mm thick, providing a compact shape for small areas. This product is super strong for its size with a pull strength of 3.9kg. It is identified by the AMF magnet part number 23012..


Uses for our Strong Neodymium Magnetic Rings:

Popular with kitchen and bathroom designers/builders, magnets provide easy construction in a concealed manner. Rare Earth Neodymium Ring Magnets are often used as a hidden fixing method for kitchen and bathroom cabinetry, as well as in benchtops. These permanent magnets can create soft door closures in a compact and discreet way. Ring Magnets provide a sophisticated alternative to the four-inch nail. Their magnetic strength is ideal for holding, fixing and releasing of different materials. These materials include stone, timber, ceramics, plastics and fabrics. These ring magnets are also regularly used as fixing methods in school science projects and productions. As well as in advertising and display companies for the purpose of presenting products, services and signage.

Excellent

I needed small but powerful magnets to hold a strait-edge on steel for a plasma cutter. They are perfect and so strong.
