Just be as careful with your left hand as with your right....put your
fingers on top & bottom, not back & front.

If it really closes to half the size as 1/250s, then you indeed have
a 1/500s in disguise....note that some seem to move a little in that
direction, but not halfway the previous width.

Those screws are also made from some silly mild/weak steel.

No, nothing that can economically be justified.
Remember, you can't cut 10 such filters from a larger screw size, as
there is only one center on the 'donor'.
Also note that for such small focus shifts, you need a very low
diopter, even more so for a wide-angle. And most filter manufacturers
stop at 0.25 diopter.
I once ran some calculations, and I recall you need at least 0.125 or
even 0.0625 (1/8th or 1/16th).
