You would need to know this dimension.

And even that won't be extremely accurate because of the lobes on the star wrence not fitting into the sharp corners of the allen socket. I usually just try a couple til I find the one that fits best.

When I was machining, we would usually get little flag handled torx wrenches with the inserts. Various sizes. I always kept them just for sacrificial set screw removal tools. Even if I had to touch them on the surface grinder to make them get a good bite in a fastener, they worked great.
