That sure beats the pocket and having to use a depth micrometer to determine stretch. I do wonder how the color changing end would hold up to thermal temperatures.

What happens if it's over torqued?

How long is the compound good for once it’s torqued? How often would these bolts need to be replaced?

You mentioned that I can be checked at a glance. Does the color change back if it loosens?

Does it react based on the stretch the threads as an approximation of the clamping force?

I have never seen this before! This is great! If it is tightened then loosened, does the indicator return to red?

So you have to use a box end wrench? A socket and ratchet wouldn’t work as u can’t see the indicator

It would be super cool to get two of these to demonstrate dry & wet torque.
