What torque is your arm rated for? It seems unlikely that any human can

There is a reason these are called *IMPACT* guns

Yabbut, methinks the 1,000# figure is calculated using Searz Foot
Pounds. I doubt a 1/2" gun would do better than 300, with a 3/4 or 1"
drive capable of doing up to 1k.

From limited experience but having done it, a 1/2 inch gun on
90-100 PSI w/ adequate flow will shear off a "normal" automotive
lugnut/stud (or lug bolt) if the nut jams or rusts on.
