I would like to have some idea what to search for for grades equivalent
to steel grades. Like what stainless bolt would I look for to be
roughly equal to a grade 8 steel bolt? A grade 5? Never mind grade 2.
Like I said, "the box stores have Hillman crap."

A search for "grade 8 stainless" on their site only shows hex nuts. In
the suggested search items it shows 18-8, but does not say if that is the
same strength as Grade 8 bolts.

Aha. Here's a precipitation-hardening bolt (17-4 PH) that claims to be as
strong as Grade 8:

There appear to be many others, including 400 Series quenched-and-tempered,
but cast a skeptical eye. A Google search on "high strength stainless
fasteners," without quotes, turned up a bunch of sources.

There's also a standard for them -- ASTM F593 -- that relates the strength
of stainless fasteners to those of carbon and alloy steels.
