Console Top Plate Fasteners

Is this a new top plate? The repop ones don't have studs that are "cut" to allow the speed nuts to tighten on to them. My console had all the speed nuts but none of them were the type with the collar around the edge like you see pictured above. So I wasn't able to get the nuts started on the studs to start cutting into them.

Out of the 50 or so speed nuts I have in my junk drawer, only one of them actually fit on the top plate studs so it's an odd size. I was able to use that one nut that actually had a collar to cut threads in all the studs. Then after that I was able to use the speed nuts that don't have a collar to install the top plate. Not sure how readily available the size is going to be at a local store. I'd personally take the top plate with me to make sure.
