That Nice Idea About Putting Thumb Screw Heads on 8-32 SHCS screws

I did it with some 4" long SHCS screws and discovered that I could not exert enough force to move the screws.  They are not very large diameter and the required force to turn them was beyond what my fingers could exert..

Since my original goal was to get the adjustment screws for the diagonal close enough to the front of the telescope that I would not need an absurdly long wrench, the 4" long screws and a standard hex wrench solved the problem adequately.  Perhaps a larger diameter head would have worked better.
