Cool new invention. SMARTBOLT

[readymix]

Neat idea, I wonder how widespread it will become.

Very neat indeed.

cool,but, how do you see it when using a socket? also i wonder how it affects strength, and would the tech limit it to lower grade strengths? very neat idea though.

 

[RockinChevy]

Neat but I don't see this being helpful when using a ratchet or impact socket. Box end wrenches will need to be used in order to see the color change as it tightens.

Don't get me wrong, I'm all for innovations and stuff but I still prefer the torque wrench over this gadget though.

bingo

most torque pulls require a steady smooth stroke to meet the torque spec. not pull stop check pull more stop check pull more. gimick at best. never mainstream.

is it just my computer, or isn't anyone else having troubles with that link,,,

i see what is being sold, or advertised, but when the page loads, it sounds like my pop-up blocker is seriously overloaded trying to stop pop-ups, and basically just jams up the browser.

and yeah, interesting idea, but i'll settle for the old fashioned torque wrench and the "feel" that's acquired over the years of hands on wrenching.

true mechanics know what i'm saying

If you have to use an impact, a torque stick is a better tool but nothing beats a torque wrench when its available

 

[sandawgk5]

I wonder if it is one time use only or if it changes back when it loosens so you can do a quick visual check to see if your fasteners are loosening up.

I was wondering the same thing... it might be like those stick on G-Meters... but once they indicate they're worthless.

That is what I am thinking.

And get your torque wrench calibrated

i really doubt that. the bolt material's deformation would have to be ENTIRELY elastic for that to be the case, and this, i think, would be unlikely. not to mention that the little plug thingy in there would also have to be elastically deformed too....

in layman's terms:
elastic deformation is when the piece deforms and returns back to its pre-deformed shape. most often, this is accompanied by some plastic deformation - that's permanent deformation after working the piece.

Very cool idea. But, how does the bolt know what torque you want to go to?
:-)



I am guessing it is just the max that the bolt is supposed to see. Black means goot-en-tite.

Could probably buy a new torque wrench for the cost of 4 of those bolts.

Interesting product for high end applications like aerospace and military. Allows for simple inspection for proper torgue. Probably won't use any of those on my old truck.

I wonder what the reliability and accuracy of those are.

i don't know if it would be good for inspection, as i doubt that the little popper piece would retract inside if the bolt loosens up and thereby doesn't have the torque it should...

 

[m-4x4-chevy]

Yeah, probably good only for inspection in a factory. Might not be usefull in the field.

Good idea though.
