I am told that my "new" 1950 Daimler has Whitworth nuts/bolts, but not sure to what extent. Can you (or someone) give me a tutorial on the differences between Whitworth and jsut standard wrenches? (I may be on of your customers soon).

Absolutely Basil,
The easiest thing for you to do is to view the attactchment I have inlcuded. There, you can see the differences between metric and Whitworth!!!

Was ther a cutoff date when the the Brits stopped using Whitworth? Specifically Triumph, I own a 69 TR6 that seems to have metric sized hardware, of late the bleeders on my brakes come to mind.

Cheers,

There are so, so many makes and models that we generally don't know as to when most stopped using whitworth but if i had to venture a guess I would say the late sixties/early seventies.

Here is a blurb from my earlier post on Whitworth that seems fitting:

"Along with his threads came heads for the bolts that were based on the length along: the side of one flat, rather than across the flats. Hence, there is no simple fractional number for the length across the flats, which is why your imperial spanners don't fit. The fractional number on your spanners refers to the diameter of the bolt which is 1/4", 3/8" etc. not the distance across the flats (which ends up being various weird dimensions). Some years later the British decided they needed a finer pitch for some applications, so another thread series was introduced (same 55 degree angle). They also decided that the heads were too big for the bolts, so for most applications they switched to using the next size smaller heads. Because of this, and to add one more bit of confusion to life, one manufacturer will mark a particular spanner "3/8BS," while a different manufacturer will mark the same sized spanner "7/16W." They fit the same diameter bolt."
