I understand that, but just because it say's mil spec, does not mean it's better than another part. You have to know what the mil spec was. This is, of course, in the report for the mils spec #.quote:
Mil-Spec means it meets the Military's specification as per whatever # they put after it.
My example would be a mil spec bolt, where the spec was for a light duty fastener. A grade 8 bolt would be a better choice in a heavy duty application, even without a mil spec.
