I saw these today at my local tool store and almost bought them. Does anyone have a set or ever used them? The sales person at the store said they just started selling them. When I asked a few questions I got some stupid made up answers. If you don't know, just say so and don't give me any BS.
My question was, what happens when you reach the rated torque setting? How do they keep you from over tighting the lug nut?
"The unique design allows the length and diameter of the torque extension shaft to flex with each blow of the impact wrench once the specified torque is reached."
What am I missing here? Expain it to a 914 kinda guy,
