I think that you understand what torque-to-yields bolts are and why they are used so I’ll just try to answer the question that’s burning in your mind...
Can you reuse the bolts and nuts utilizing one of the smart re-installation methods outlined and not have any problems near or far term?
Short answer.. Maybe.
I’m not sure any of your re-torque methods will get you back to the desired torque and in the desired elastic range of the bolt originally specified by engineering for the installation. Also, it is not uncommon for the threads to yield and on removal you end up with a sheared or broken bolt.
Personally, I think trying to second guess the engineering without detail data is --- well not engineering.
So, it’s only $240 to do the job to factory specifications?
