Our offering for anyone looking for a strong 3/16" diameter neodymium magnet. Nickel plated for a shiny, silver finish. Useful for a wide range of 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 N52 as part number D31-N52 and in grade N42 as part number D31.
