What size is the bolt that holds fan blade on Coleman Mach 15 AC blower motor?

I’ve replaced fam motors on (2) of (3) units. It is a torx 30 , conventional lefty loosey. Hold the blade and use a drill or impact driver with a torx bit. A set of torx bits will always come in handy.

Evap fan was a t handle allen for the longer length reaching through the fan. The condenser fan blade was a clamp with a sheet metal screw through the clamp. The Allen was either 9/64 or 5/32. I found the evap fan blade was not close enough to the evaporator and was drawing air around the side of the blade instead of the evaporator. Make sure when you put the fan blade back on that it is as close to the evaporator as it can be without rubbing on the Styrofoam.
