That's FUNNY, but here's a true story. "Back when" the automakers were screwing with metricizing our cars, a mechanic came into the parts store, having just left our fasteners store. He had a bolt with a 10MM head so he KNEW it was metric, but nobody could ID it. He was a line mechanic an the CHEVY dealer. I finally smelled a rat, and sure enough, it was a standard 1/4" bolt, NC thread, with a 10MM head on the thing. THANKS GM!!!!
