Re: Fasteners: Black Oxide or Zinc Plated?
The finish really doesn't relate to the strength. Mil-Spec gets you quality control that your average bolt doesn't get, but unless it is surplus, you are also paying for documentation you don't need. Cadmium is more expensive because of environmental issues. You really don't need it unless we finally get a water game.
