Smartbolt tells you when to stop screwing

Smartbolt tells you when to stop screwingMankind lives in such an amazing techno-golden-age that even the bolt is getting smart. That’s why it’s called the Smartbolt, it’s equipped with a tiny indicator disk on top that shows you just how tight it is. No fancy electronics, just a simple visual tension indicator that starts out red and turns more black as it gets tightened. Looks like a nipple, which makes sense. Mine would turn colors if you gave them a twist too. They even have a more-precise version that goes from yellow to green when 90% tight, then black at 100%.

This is a great invention, mostly because torque wrench’s tend to be large and hard to maneuver in tight spaces. If we can get regular screws to do this, that would be awesome.
