I had a small job and one of the items was to turn flats on some set screws. The set screws are 1/4-28 x 3/16". not much to hold onto. I made up a fixture out of a 3/8-16 coupler nut, 3/8-16 screw and some CRS.
One end of the nut was turned to remove the flats. The head of the screw was turned for clearance when in the lathe chuck. I turned and bored a cap out of CRS to press onto the coupler nut. The cap was drilled and tapped for the 1/4-28 thread. The end of the screw was turned to clear the ID of the threaded hole. The screw is used to set the depth of the set screw and to keep it from turning.
