This is one of our most popular sizes. This is a great size for general purpose hanging and a wide variety of magnetic applications.

The SH grades have a maximum operating temperature of 302ºF (150ºC), as compared to standard N grades that have a maximum operating temperature of 176ºF (80ºC).  These are great for applications where you need to place a small magnet in a high temperature environment.

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