FAQs

When would I choose the .625" stud over the .50"?

Go longer when the threaded hole on your device is deeper, so the stud bottoms out and seats the ball firmly. The thread itself (1/4"-20) is identical.

Which RAM arms does it fit?

The 1" ball fits any B-size RAM® double socket arm and any B-size socket base.
