Hello Kelley. The black set screw is 1/4" and requires a 1/8" allen wrench. They are definitely easy to misplace. A lot of times people will think they are missing, but they are actually deep down inside the coupler and very hard to see. If you shine a light down in the hole and see black, the set screw is down in there.
