Often, we are trying the increasing or enlarging concepts.
But, here, no pills or other strange accessories needed! ^_^
will help you by a useful reduction!
Reducer for thread 5/8" to 3/8"
With its internal female diameter of 3/8" and its external male 5/8" diameter, you will be able to screw this small adapter in any device with a 5/8" female thread (as some microphones, LED lamps, flashes, monitoring screens, controller...), and fix the accessory on your tripod, its quick release plate or any other supports with a 3/8" male thread.
And, if your support has a smaller and standard 1/4"-20 male thread, insert this other Adapter ADP-38M14F inside the present ADP-58M38F, as below.
The photo below shows the Adapter ADP-38M14F screwed inside the ADP-58M38F.
This allows a conversion 5/8" to 1/4"
A very useful accessory, all in metal conception.
