grade eight?

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.
