Eaton / Cutler Hammer Main Lug Torx?

I don't use a lot of Eaton / CH products, but I did install a mbeb200bts today with a csr2200n main breaker. This panel uses what appears to be Torx lug screws. I bought a brand new T40 Torx bit and it fit pretty good, but I was only half way to the required torque (250 in lb) when the T40 stripped out. Does anyone know if Eaton does use T40 torx, or is there some special tool I am missing? I looked all over their online papers and can't find any reference to the tool size. Thanks in advance.

My recollection is to use a good regular screwdriver, but you have a 200 amp, it might be an allen. What do the panel instructions say?

The panel instructions and everything online and at Eaton is crap. Can't use a screwdriver, no slot, and I have to torque the lug. It is definitely not hex/Allen - no flat sides inside. Looks like Torx or Spline. Like I said, T40 fit pretty good, with minimal wiggle. But trying to get 250 inch pounds ... no way, the inside spun out like butter. Thanks ....
