برغي قاعدة الحامل ثلاثي القوائم القابل للعكس من Promaster - 1/4"-20 و 3/8"-16

Finally got this after misplacing the original bolt—the reversible design makes it easy to switch between 1/4-20 and 3/8-16. It screws in smoothly and holds my tripod head securely.

Lost my original mounting post on a shoot and panicked, but this replacement flips perfectly between the 1/4-20 and 3/8-16 threads. Fit my tripod base like the factory one, and the threading feels solidly machined. Glad to have a spare now.

This tiny bolt saved me from having to buy a whole new tripod — the reversible design works perfectly for swapping between my smaller camera and a heavy lens setup. Fits snugly with zero wobble once tightened.
