This strong size is great for when you need a step up in strength from the 1/4" D44 or D44-N52 magnets. They are managable, but can pinch slighty if they are not handled carefully. These cylinders (a.k.a. "rods") make great, high-power fridge and bulletin board magnets. Try some today!

This size is also available in grade N52 as part number D55-N52 .
