The Small and Medium MagNut set is a magnetic quick clasp specifically designed for the KeyBar but works on tools or other pesky items for which you need a quick mounting solution. A set includes two MagNuts (a right and a left MagNut) each with a 1/2″ diameter split ring. NOTE: Magnuts made of brass & copper – the material does create a patina on the surface of the product.

MagNuts come in a choice of small, medium or large aluminum, small brass or small copper MagNuts with pressed 1/4″ x 1/4″ rare-earth (Neodymium Iron Boron in Grade N52) magnetic cylinder insert, which has a pull force of 6 1/2 lbs. Medium aluminum MagNuts have a pull force of 18 lbs.
Note: These rare-earth magnets will lose their magnetic properties if heated above 175 degrees Fahrenheit (80 degrees Celcius). The strong magnetic fields of these rare-earth magnets can damage items such as television, computer monitors, credit cards, bank cards, computers, data carriers, video tapes, mechanical watches, hearing aids and loud speakers. Pace-makers may be damaged or switch to “Test-Mode” in the presence of a strong magnetic force, if a pace-maker or other bodily implant is in use, keep a minimum of 3 feet distance. Keep away from small children. Under no circumstances should you try to cut, saw or drill the rare earth magnet as the resulting dust is very flammable. You should also not burn the magnet as it will create toxic fumes.
Brass and Copper MagNuts do aquire a patina and may not come as polished as shown in photos.
