I agree. I have bought 316 stainless hardware from Marsh Fasteners and they do that as well.Samuel, they probably have several lengths available and just one photo for all of them. I would not be concerned.
Dan,I think the chance of galvanic corrosion is greater when moisture is readily available as in marine applications. This is where I learned to avoid using copper anti seize with aluminum and stainless fasteners.
Maybe it's not an issue in a cook box where its hot and greasy.
I use copper anti seize all the time on steel. The bottle I have is probably 30 years old.

Yea, even if there’s a lot of crud caked around the burner tube bolt and the burner tube won’t pull out, I’ve done this before:I have never one time tried to remove the burner tube bolts from a cook box, so none of this makes any sense to me and I've had to take the burner tubes out of a lot of cook boxes. I just don't want anybody to think that this is normal practice, because it's not, they are not meant to be removed.The bolts that hold the drip rails on are another story. You do have to remove those to replace rotted out drip tray rails and you can end up snapping those off if you aren't careful, though it's never happened to me. Last are the manifold bolts, if they don't want to come out of the cook box just leave them also. There's no reason to risk damaging anything trying too hard to get those out of they are stubborn.
