I do not want a stainless steel fastener. I know that stainless steel and aluminum do not play well together.

I don't know why many replies seem to assume that is what I am looking for.

I am only able to find stainless steel. But want just a normal grade 8 fastener, possibly zinc coated, or black oxide, the finish isn't my main concern.


"I can find them in 18-8 Stainless, but I would really like to have Grade 8." quoted from your opening post.

This could be understood that you wanted grade 8 Stainless, and you have now cleared that up.

I am surprised you found Grade 5, Good luck in your quest.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
