Michael Q. ★★★★★ Oct 20, 2026

The brass construction feels sturdy in hand, and the threads on both ends threaded smoothly into my gear without any wobble. This little adapter solved a compatibility issue perfectly.

David G. ★★★★★ Oct 18, 2026

Solid brass construction gives this little adapter a reassuring heft, and it threaded smoothly onto both my tripod and a 3/8-inch accessory without any wobble. Exactly what I needed to bridge the two common thread sizes.

Elizabeth ★★★★★ Oct 18, 2026

Exactly the piece I needed to adapt my 1/4‑20 accessories to a 3/8 mount, and the solid brass gives it a nice firm weight that feels dependable. Threads were clean and tight on both ends, so no wobble once I snugged it down.
