OK then. I stand corrected. My last Japanese car was an RX-2, which bit the dust in 1981. Since then it has been VW, Saab, or now I am a real sucker for Alfa Romeo. Still... All tools, machines, bikes, pretty much every hex head I have experienced here in Europe, uses 10, 13, 15,17, 19, etc. I own lathes, table saws, milling machines...not to mention bicycles. Never seen a 14mm hex head. But I haven't owned a Toyota!
