Mia ★★★★★ Oct 20, 2026

The dual threading is what sold me—1/4-20 on one end, 3/8 on the other, so I can switch between two of my rigs without digging for adapters. Brass feels properly hefty in hand, not flimsy. Exactly what I needed for a solid connection.

Ryan ★★★★★ Oct 19, 2026

The threads on this little brass spigot are machined perfectly smooth, so screwing it into both a 1/4-20 and a 3/8 mount was effortless. It feels dense and sturdy, exactly what I needed to connect my flash bracket.

Finally, a solid brass adapter that doesn't feel like it'll strip the first time I use it. The threading on both the 1/4-20 and 3/8 sides is smooth and precise, so it screws on easily and stays tight. Exactly what I needed for joining a couple of light stands together.
