I understand what you are saying, but I only care about the ones that failed, not the ones that didn't fail. I guess the next step would be to get off my *** and look at what the ratio of red to black interior is. That way I can make sure the failure distribution is significant. Just from comparing the parts I have here, the red screws are different than the black, they feel more brittle. Even the marks where the retaining clip sits are more significant on the red than the black.
