The DCC1003 Phidgets have two white plastic hexes on the left/right halves of the black heat sink.

They don't seem to be mentioned in the documentation anywhere.

What are these hexes for? Are they just mounting screws for the heat sink?

If you look on the underside of the board, you can see that they're simply an easy way to hold the heatsink in place.
