I bought some 4140/4142 1/2" hex stock from McMaster (
#6607k34) two years ago. I just measured out a ~1" long scrap piece at .4915-4925" flat to flat (nominal tolerance is +/- .007") on some cheap digital calipers. As you'd expect, the shaft fits into VEXPro gears easily, but with noticeable backlash.
