What is the thread pitch and size of a Schrader valve on an inner

If the pin is bent sufficient to make core removal difficult, I'm not sure
you have many options other than using a precision screwdriver to force the
pin straight again so you can get the core-tool on it.

Have you considered simply replacing the tube? Tubes aren't particularly
expensive, or particularly hard to replace. Assuming this is a bicycle or
other uncomplicated piece of machinery...

Replacing the tube was a bear -- see my "Mounting a Small Tire on
Wheel" post -- but I finally succeeded. But, in that process, I
must've bent the pin.
