Anyone know what GD uses these screws for?

Found this laying on the floor at the back of the island (the rear of which is separating) when I got to GD's Middlebury site today. Looks like it was under the slide overlap because there is a gouge in the linoleum floor in direct line with where the screw was laying. No gouge on two prior nights.
Thanks,
John

Never mind - found where they go. Pins that screw into the stove top grates that fit in the rubber grommets on the stove top. How that got from the stove top and under the door side slide-out I'll never know.....
