Photographers who place a premium on being well-prepared will want at least one 50mm-long Female Threaded 3/8" to Male 5/8" Stud Adapter from Impact. This indispensable adapter will give you additional mounting options resulting in faster set-ups. The bottom of the adapter features a 3/8" threaded opening for attaching to the 3/8" screw on a light stand or other item. With the adapter attached to a stand, you can mount a light or other gear with a 5/8" receiver. For strength and durability, the adapter is made of chrome-plated steel. And at only 3.2 oz, it is easy to pack one for each light or stand.
