Clinch Nuts
Clinch Nuts
Clinch nuts are threaded nuts that allow quick assembly of the
transistor to the heat sink. A single screw mounts the transistor
to the heat sink, reducing your hardware requirements. Clinch
nuts are permanently pressed into the heat sink, and come in a
variety of English and Metric threads–CNE designates an English
thread, and CNM designates a Metric thread.
