These may have been around for a long time, but it is new to me. Very cool if they work as advertised.

The only way of discovering the limits of the possible is to venture a little way past them into the impossible - Arthur C. Clarke
I never heard of it either...Apparently it's a product of Industrial Indicators...Dave may have more info......Ben
On edit, that could be a real advantage in an application like high-horsepower engines such as drag racing or tractor pulling where headbolt stretch is common...In the Air Force we safety-wired most bolts after torquing, to prevent movement with vibration in flight, but safety-wiring would not compensate for fastener stretch...

I have not seen them before either. It gives an instate indicator to anyone checking the torque---without having to go back on them with another torque wrench.
Down sides: An over torque would not be obvious and I'm afraid the cost would limit their application.
