There are a few car parts that despite the widespread adoption of the Metric system remain sized in English units as international standards.
Think about it - A few of the known parts in the next post... |

QUOTE(ArtechnikA @ Aug 26 2008, 07:57 AM)  There are a few car parts that despite the widespread adoption of the Metric system remain sized in English units as international standards. OK - for those of you playing at home, we have 1) Wheels (e.g. 15", 16" ...) 2) Brake caliper mounting bolt spacing (per the brake thread) - 3.0" and 3.5" 3) Brake master cylinder bore. Our "19mm" is really a 3/4" bore, and the other familiar sizes (17mm 20,5mm 23mm) are actually sized in 16's of an inch 4) Seat Belt mounting bolts. They are really 7/16-UNF (24 tpi). This is close to an 11mm 1,0 to about 3 decimal places so they're effectively interchangeable. But 7/16-24 they are. |
