ProMaster 小型ねじアダプター – 1/4″-20メス→3/8″-16オス

I needed a tiny adapter to mount my flash onto a heavier light stand, and this one fits perfectly—brass feels solid, no wobble. The knurled finish gave me enough grip to tighten it by hand without any tools.

The knurled finish on this little brass adapter makes it really easy to tighten by hand, even with cold fingers. No more wobbling when I mount my softbox—solid connection every time.

Finally, a way to use my heavy-duty light stand with smaller gear. The brass build feels solid and the knurling gives just enough grip to tighten it securely.
