Ford doesn't use such screws. The high-low dual helix screws main
advantages are that they have plenty of strength, do minimum damage to
the plastic, and are easily removable. Ford prefers to stick things
together with glue, putty, and Tinnerman clips, all of which have
lousy strength, destroy the plastic, and a PITA to remove.
The screw in question fits various Fluke DMM (digital multimeter).
