British standard whitworth lives on as the thread which attaches cameras to tripods I think.
I once liberated some simmilar bolts from a broken out tunnel wall at Tottenham Court Road. We machined into tensile coupons and they just stretch out like pulling a toffee bar!
It's amusing these days to think of imperial measurements as a great standardising force in the world in light of our inability to go metric.
- bunabhucan 2y agoHercules in India still sells roadster bikes with Withworth threads.
- analog31 2y agoYup, and the eternal Sturmey-Archer AW 3-speed gear hub uses Whitworth threads too. I've got a couple on bikes. It's not a problem because the parts are unique anyway -- there's no other use in the world for an indicator rod, or guide nut, and the outside of the nut is close enough to 15 mm.

Another early standard thread was the British Association. Proposed 1884, and adopted 1903. It was the recommended thread for small diameters (even by the British Standard institute), and is still seen in electrical terminals, and some small instruments. BA threads are metric!
- fecal_henge 2y agoI didnt know that. I kept all my BA eyelet crimp terminals as they were a pretty good fit for metric threads, I see this is not a coincidence now!

- fecal_henge 2y agoThats BSP no?
- _fizz_buzz_ 2y agoBSW is the basis for BSP. BSP is specifically for pipes but has a BSW thread.
