[Shop-talk] What's the deal with impact torx sockets?

[Thomas Coradeschi]

I would not use an impact wrench on this (it’s 3/8” drive, the smallest 1/2” drive torx they have is T45). Breaker bar and a cheater if needed.

I just want a set that I can use in an impact gun and remove a bolt without breaking every time.  I would want a complete set of sizes, but it seems that I always break the T40 first (it seems to be the most common size.)
