The Kupo KS-077 5/8" Stud with 1/4-20 Male Thread is a 3.5 inch long 5/8’’ baby stud with a 1/4’’-20 female thread.

This stud is designed to convert a 1/4" thread, as commonly found on the end of a light stand or microphone boom to a 5/8" stud, the standard stud for mounting a studio light or video light. The file thread gives extra grip to prevent your light from rotating on the stud.
