I have never checked mine. I understand that they yield (elastic) at the specified torque, so an impact will simply bounce against he spring once the proper torque is met. I bought mine after having a set of tires mounted by a truck mechanic (on a coach), using his 1" drive impact, I asked him what torque he was using, he replied "tight is tight, too tight is broke". He broke three studs and cost me about $300. From that point on I had tire service use my torque stick, no future problems, and I torque them by hand (50# torque wrench on an X-12 reduction wrench) otherwise.
I don't think I'd use one for installing something like a glow-plug, but your suggestion to use one to limit the torque of an impact extracting it is IMO better than counting on the impact wrench's limit.
I consider the torque-stick to be more of a safety than an accurate instrument for installing threaded fasteners. Torque-wrenches still work better for me, perhaps I'm old-fashioned there.
