In the past year, and I've not gotten all that much time in my shop in this time, I've also run into 8-36, and 1/4-25, and several smaller metric screws, plus some more microscope screw holes I've not managed to figure out yet. Anyone working on antique American or Japanese sewing machines, for example, will need a bunch more, too. Retro's method will work for anything you have or can make a nut for.

Not to mention that if you had one of those with holes for 1/4 and larger screws you would need a 400 pound gorilla to squeeze the handles for you.
