Wrong guess. Those sticks will twist like a torsion bar when the torque us reached. There is nothing to click, they're solid metal. Take note that the higher the torque the larger each stick diameter. Impact guns aren't 100% torque, it's a hammer hitting a block of metal that tightens with each hit. Once the torque is reached the stick absorbs each impact by twisting, not allowing it to tighten ant further.
So is you won't hear a click when tightening, if you DO, that's the sound of your lug breaking.
