What size nuts do I need?
I have these 5x16mm screws for my car accessory but I don't know what size I need for speed nuts, spring nuts or "U" type nuts, however you want to call it. The nuts were all in even number sizes like #6, #8, #10 etc. My guess is #8 but not exactly sure. Can anybody help me?

Welcome to the forums! Yep, you are comparing apples to baseballs, and you won't get fruit salad no matter how much you work at it. You have metric bolts and are trying to sae or american nuts on them. Won't work. You will have to match either the bolts to metric nuts or change the bolts to sae or american threads, which use numbers like 6, 8, etc.

Oh, so if I want to match the nuts to my current 5x16mm screws I would have to look for M5 nuts? Is this the right size M5, what about the numbers after M5x## I've seen couple of those but wasn't sure.

If the numbers are something like .8 (course thread) or .5 (fine thread), that is exactly what they are, thread pitch designations
this is similar in function to sae standards like 3/8-16 or 3/8-24.
Now there are other numbers used on bolts such as 5, 8, and 10 which are hardness notations.
