: Try this.Heat up the hex head end of the bolt (or other fastener) until barely a dull red, and immerse the bolt into used engine oil.The head of the bolt will take on a dull black finish that rivals the raven finish.

Larry,Thanks for your suggestion!I've tried this before and it works well.
I haven't been able to come-up with a good way to heat more than one nut or bolt at a time.Which make it very time consuming to do a whole project.And I've often wondered; "How much of the temper do I take out of the bolt when I heat it".Should this really be a concern?Thanks again.
