Console Top Plate Fasteners

I just rebuilt my console and the original little nuts are hollow sheet metal, but installed the opposite way from the nuts shown - the hollow side sticks out, not toward the plate.
They are on backwards if the hollow side is showing. But they will work that way, it's just that the flange of the nut is not supported against the part. Below is a photo of a palnut, speednut, and U or J nuts.
