| OK, metallurgists. I'm looking at a set of jack stands and the pins are made of #20 steel. What does that mean? I've determined it's probably a China grading but haven't been able to find anything (that I could understand). How does the numbering system show strength, etc.? Just curious, Dave W. ------------------------ spridgets@autox.team.net Archive: http://www.team.net/archive |
