My mehcanic said I need a 10mm wrench for car repair I need to do. I can find 3/8" wrenches that say No. 10, but 3/8" actually is 9.5249999mm. I see wrenches that just have "10" stamped on them but no additional details. I'll be adding manual trans fluid to my 93 Ford Escort. The hardware/retail stores I have been to seem to be clueless, and I certainly have no idea if these tools are interchangeable, or if I should be looking at something "specific".
