Thank you for your comments and ideas.
I thought stainless steel was harder than steel, so the grades were higher. wrong idea
. But cool, now I know it isn't, and I will not do the same mistake a second time. Thanks!
I tried another hardware store which has more or less everything, and same : their 12.9 grade bolts are black, exactly as the ones I have. So I think I'm going to use these ones for now, and check how they last.

Funny you wrote that on my thread the same day I wrote
on another thread that I would not weld the roll bar because (as Porkchop says here too) of the fuel tank

Are you sure? I think they are pretty exposed to the elements: water/mud/salt from the wheels on the underside, and rain/sun (and snow
) on the top side.
But thanks for the inputs :-)
