tripod mount and screw like?

[Steve Smith]

Perhaps in England the Whitworth form was used.

And Germany and Japan.

Steve,

Ah, I suppose camera/head vintage now becomes important. I was basing some of mine off of the measurements I took from my cameras and fittings. It would make sense that a really old camera would have a different threadform.

My original understanding was that the discussion was counting diameter and pitch as the important pieces of a screw, not the form; rather than the idea that diameter/pitch has been relatively standard but threadform has changed.

As long as you don't do it up too tight, you can get away with a UNC screw in a Whitworth thread but eventually it will wear more than the proper mating threads.

When I looked into this a while ago I found one tripod manufacturer who specified UNC and another using Whitworth so there doesn't appear to be a standard.

Likewise, there is probably not a standard with cameras but I suspect that German and Japanese manufacturers are using Whitworth as that's what they were using before UNC existed.
