I hate to tell you this... but you know what grade it is by buying them
from a source that can provide this information. Generally, if they're
zinc plated, they all look "pretty"... I'm not aware of any markings
that would tell you after the fact, but then, I haven't sat down and
compared them either. Maybe someone has?
There are many different grades. This is something that you have to
take seriously. If the application calls for grade 8 bolts... It might
be a good idea to match them with grade 8 nuts, etc.
Someone else mentioned buying them in bulk from a racing supply
company... This would probably be the sort of source that would know the
difference! There are also nut/bolt suppliers out there, even through
the web.
