not that i'm any expert with nuts...sorry... can't stop the laughter....
but i always use a cupcake tin with a grease marker to label the bolts/nuts/screws and where they came from, just don't tell the "kitchen goddess" what you used it for.
just follow the opposite path and bam.... i got tired of doing the same thing that's happening to you, and then thinking about it on the freeway was enough to give me cold sweats and white knuckles....
good luck.
