Will a nut cracker such as this split a flanged nut?

The torx-head end of the top of my strut split, and now I can't get the nut off. My locking pliers aren't strong enough to keep the shaft from spinning, and the shaft is too smooth for a pipe wrench. I want to try the cracker before I have to get an impact wrench. The strut is bad, so it can be damaged in the process.
