grade eight?
I would say no. The lower bolts I have seen had that slightly dark gray
tinge to them, indicating Grade 10 or better IIRC.
You can't have them too hard, I know that for sure... :D

I was curious, so I checked. Three dashes on the head- so grade-5? That
should be strong enough for the lower strut bolts, right?
Thanks for clearing that up though about stainless hardware.
So if we need really strong corrosion-free hardware, what do we do?

The hardware store misled
you.
Stainless steel bolts are generally (there
are several alloys) rated at min 70,000psi tensile.
Even grade 5 hardware is rated at min 105,000psi
tensile.
Grade 8 is around min 150,000psi
tensile.
There are no grade 8 stainless
fasteners.
Do NOT count on stainless hardware to be
especially strong stuff, guys....it is only more resistant to
corrosion.

I went to the hardware store
and got some grade-8 stainless bolts to go in their
place.
