Kupo 六角螺柱 3/8"-16 M 及 1/4"-20 M

The hex shape gives me a solid grip for tightening by hand, which is nice. Only wish it came in a slightly longer length for thicker setups.

I needed an adapter to step down from 3/8" to 1/4" for a light stand, and this stud did exactly that with solid threading. The knurled grip makes hand-tightening easy, though I wish it had a bit more length for thicker plates. It’s a simple, well-machined piece that does the job without fuss.

The double-ended design with both 3/8"-16 and 1/4"-20 threads makes it really versatile for mounting different gear. I just wish it came in a slightly longer length for some of my setups, but it's solid for most standard uses.
