RAM® Tough-Ball™ 附 1/4"-20 x .375" 螺紋螺柱 - C 尺寸

The 1/4"-20 threaded stud threads perfectly onto my camera rig without any adapter needed. It really locks down tight, no wobble at all.

Finally, a ball mount that doesn't wobble—this one grips my accessory base tightly with no play. The threaded stud was a perfect fit for my existing setup and took less than a minute to install.

The stud's threads are machined clean enough that it screws in smoothly without any wobble once tightened. I've been swapping it between two different mounts, and the ball holds solid every time—exactly what I needed for a secure base.
