Ryan Z. ★★★★★ Oct 20, 2026

Nearly lost mine on a shoot last week and was relieved to find this exact replacement. The reversible design is so handy—I can finally switch between 3/8"-16 and 1/4"-20 without hunting for adapters. Threads engaged smoothly and it feels just as solid as the original.

Stella U. ★★★★★ Oct 19, 2026

Flipping the bolt between 1/4"-20 and 3/8"-16 takes two seconds, and it threads into my tripod head without any wobble. I grabbed this as a backup after a long hike nearly cost me the original, and it fits like the factory part.

Lost the original bolt for my travel tripod and this one fits perfectly. The reversible design is clever—just flip it to switch between 1/4"-20 and 3/8"-16, no adapter needed. Solid build too, no wobble once tightened.
