Were the "Squab" employees using torque sticks when they used their air guns? Torque sticks actually prevent them from hammering over their rated torque.

They're pretty accurate in my experience and we use them at work. We occasionally verify that torquing is equivalent with a torque wrench to ensure the metal hasn't fatigued beyond usefulness.
