The GTX Male 1/4" with 5/8" Socket is a very useful accessory to have around. It is a 5/8" socket with a 1/4 x 20 threaded stud on top. Because motion picture lighting is portable and many light stands have a 5/8" spud, also known as a baby spud, this socket would make for the perfect accessory to mount a light. However, it does have many other uses. Accessories can also be mounted onto the threaded stud on top of the socket, and when you combe it with additional adapters, it can be compatible with most clamps.
