Here is a link for anyone who wants to dig deep in what the big boys put into their space toys....I had a chuckle where I read about black oxide finishes being for appearances only with the only corrosion resistance was the oil put on it, and lock washers once flattened out become just regular washers and their locking capabilities are almost non-existent.
