The NASA fastener handbook specifically calls for using silver plated nuts on steel bolts for aerospace. Very cool. >Silver plating is cost prohibitive for most fastener applications. The big exception is in the aerospace industry, where silver-plated nuts are used on stairdess steel bolts. The silver serves both as a corrosion deterrent and a dry lubricant. Silver plating can be used to 1600 “F, and thus it is a good high- temperature lubricant. https://ntrs.nasa.gov/api/citations/19900009424/downloads/19900009424.pdf https://ntrs.nasa.gov/api/citations/19900009424/downloads/19...
