This is one of our most popular sizes.  In grade N52, they are even more powerful than our standard grade N42 D42 discs. This is a great size for general purpose hanging and holding and arts and crafts projects.

This size is also available in grade N42 with black epoxy coating as part number D42E, in grade N52 with black nickel plating as part number D42B-N52, in grade N42 with silver nickel plating as part number D42, and diametrically magnetized as part number D42DIA.
