These adapters are machined from solid brass and help connect all of the other grip items as well as lights, cameras, tripods, etc… Think of them as the ‘glue’ in the world of grip. Yes, they are all 5/8” compatible.

Why brass? It doesn’t rust. Also it is softer than steel but with a high shear strength. So when a brass stud or spigot is used in a 5/8” receiver, the receiver’s set-screw can ‘dig into’ the brass a bit creating a very strong bite. That prevents the stud or spigot from turning or falling out.
