Title: Question about the thread size on these table clamps at B&H
Post by: su6oxone on February 26, 2009, 10:19:24 PM

Maybe I'm retarded but I can't understand if this AKG clamp has a 3/8" stud on top or if the stud is 3/8" and the thread is skinnier (looks small, like 1/4").  Anyone have this or can help clarify this for me?  Thanks!

And this one doesn't say what size the thread on top is...

The top one is a standard K+M clamp with the international standard 3/8" Whitworth thread.

The bottom one looks like it also has the standard 3/8" Whitworth thread - but with a 3/8" to American 5/8" adaptor screwed to it.

If you put a 3/8" > 5/8" adaptor on top of the Whitworth thread will it completely cover the bottom, non-threaded, portion of the Whitworth thread as well?  I like that one but wouldn't want that little bit of non-threaded part sticking below the adaptor.

Nope.  The threaded adapter will screw down to the bottom of the 3/8-16 thread / top of the unthreaded base.

Why not?
