Solderable Pins / Solderable Nuts
Solderable nuts are permanently swaged into the heat sink
for quick pre-assembly with the transistor. Screws are used
to mount to the heat sink and are installed from the top.
Solderable nuts feature a closed end that prevents solder
from wicking into threads and trapping contaminants or flux.
Heat sink and transistor are then handled as a single compo-
nent and dropped into plated-thru holes in the PC board for
wave soldering. (Solderable nuts require slightly larger printed
circuit board hole sizes)
Pre-mounted to heat sink at factory
Ease of pre-assembly in production

Solderable Nuts
Note: If a part number requires 2 solderable nuts, simply add a "/2" after the solderable
nut character suffix on Thermalloy origin parts.

Vertically mounted, extruded heat sinks are
converted to wave solderable with the addition
of solderable roll pins. Roll pins are available
with stand-off shoulders in different heights
for easier cleaning after wave soldering.
