I am working for a company that produces military hardware and I am having a hard time convincing anyone here that the use of a flat washer is necessary when fastening irridited aluminum parts. They insist that only a lock washer is required. I have shown them the result of using no flat.....pitted and chewed parts from the locks. I have searched everywhere to find a document to show them something that supports my position. Also, we stainless hardware from #2 to 1/4' machine screws. Would it not be better to not chew up the irriditing and allow electrolisis to start? If the irridite is not comprimised a better resistance to dissimalr metal corrosion? Most of our stuff is used in salt air and other harsh environments. Any info would be appreciated greatly. Thanks Rob WD4DUI@bellsouth.net
