Same size? Well yeah but "Whitford is British Standard", as you said, is not true bc why have two dimensions for the same item if they are identical? If my 1/2 socket is also 13mm does that mean the SAE standard is metric? Socket should be stamped "1/2sae13mm, then. Just saying...
No, SAE and Metric are physically different sizes with BS you are dealing with thread pitch.

The man responsible for the development of the first standards for the production of threaded fasteners Is none other than Joseph Whitworth. In 1841, his paper, "A Uniform System of Screw Threads", set forth a concept that was to revolutionize manufacturing.
His idea was simple:
Each diameter of bolt or screw will have its own number of threads per inch (TPI)
The angle between the side of one thread and the adjacent thread should be 55°.
Both the crest and root of each thread should be rounded.
The relationship of the pitch to the radius of the rounded portion of the thread is defined by a ratio of l/6th; in other words, the radius r = (1/6) x (pitch).
Finally there was a system. If adopted, that would allow the fasteners used on one type of machine to be replaced with another "standard" fastener. The logic was hard to beat, and England adopted the system to the extent that by 1881 it was the effectively the British standard

Naw, I have enough to do whatever I need, not much of it mind you but its very rare you need them unless you work on old English stuff. I used to mess with old English bikes that's the only reason I have them.
BTW The King **** brand were good tools. What a name for a quality tool, I would expect that from China.

Thank you Trav-
BS refers to bolt head diameter while Whitford refers to bolt shank diameter. Hence the confusion (on my part).
The British thoughtfully marked their socket/wrenches using both to confuse us to get even for that little incident in 1776, LOL

It was a very different system alright compared to what we have today. I like Metric its so easy especially using precision measuring tools.
It's nice to see some real tools for a change of scenery.
And by the way guys, Snap-on has never used a capital O in it's entire history of doing business.
