Ford used SAE fittings on the 2002 Duratech. The jacking thread used to remove the fan pulley is 3/8"-16 and the transmission mounting bolts into the transmission are 1/2"-13. They about drove me nuts finding compatible bolts.

Speaking of "metric", there is a guy on the net (Dave Williams, who seems to be well versed in such things) who claims there really is no metric standard, at least as far as bolts and nuts are concerned. The standard specifies only for the bolt to be specified in metric units, i.e. there is nothing that states a bolt cannot be say, 12.682 mm and the thread 1.96mm. If that is true, then yes, they probably ARE metric!

I read somewhere, years ago, that the old British Whitworth thread nuts and bolts/machine screws were superior to SAE, UNF, metric etc. Something to do with the thread profile.

Can anyone throw a light?
