This brings to mind a question I have had for a long time.
Our local supply store (USA) carries Grade 8 (gold), Grade 5 (gray),
and the common (standard-silver) bolts. My question is what grade are
the common bolts? Or dont they grade them?


Unmarked bolts are usually grade 3, or worse.


I'd guess they flunked Kindergarden.
