Kbob,
The screw was installed to cure a short arbor. The arbor is supposed to bottom out in the barrel assembly so the wedge is not the deciding factor in adjusting the barrel to cylinder gap. With proper fitting, accuracy and consistent dimensions are maintained. When fit this way (proper arbor length) the wedge becomes a thumb pressure install/removal.
